[SOLVED] Error in/invalid pointer with numerous Qt applications

I re-installed the qt5 group from the official repositories prior to re-producing this issue.

Recently, I've noticed several Qt applications crashing, some when starting up, whereas others only after clicking on certain elements within their UI. The error will look something like the following

*** Error in `/usr/lib/sigil/sigil': free(): invalid pointer: 0x00007f8d403323c0 ***.
*** Error in `/opt/mendeleydesktop/bin/..//lib/mendeleydesktop/libexec/mendeleydesktop.x86_64': free(): invalid pointer: 0x00007f2be6aad3c0 ***
*** Error in `qgis': free(): invalid pointer: 0x00007f24484493c0 ***

I'm stuck as to how to better pinpoint the source of the issue here. I've tried running with strace but didn't get much more information from that. Any suggestions? Thanks.

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

gdb will get you more information - (at least which library is responsible)

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

As I had suspected, it looks like it's from libQt5WebKit.so.5, though I'm not sure what to make of it.

Hard to say - there's an abort from thread 1, but you only posted (waiting) #18 and top of #17 tongue

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

Java plugin.

pacman -Qo /usr/lib/jvm/java-9-jdk/lib/libdeploy.so

Tried jdk8?

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

pacman -Qo /usr/lib/jvm/java-9-jdk/lib/libdeploy.so

/usr/lib/jvm/java-9-jdk/lib/libdeploy.so is owned by jdk-devel 9.0.1-1

Ok, I see that in the trace, but why is Java 9 being used? My default Java points to java-8-openjdk

archlinux-java status

Available Java environments:
  java-6-jdk
  java-7-openjdk
  java-8-jdk
  java-8-openjdk (default)
  java-9-jdk
  jdk1.8.0_131
  jre-7u71-x64

print $JAVA_HOME

/usr/lib/jvm/java-8-openjdk

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

It's probably trying to load all installed verisions.
You could try to set QTWEBKIT_PLUGIN_PATH, but those path patterns might even be hardcoded ...

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

So this is just some configured directory that isn't derived from some environment variable like JAVA_HOME or LD_LIBRARY_PATH? Seems counter-intuitive, and it since it seems like many users might have multiple versions of Java installed. I guess the highest numerically would take precedence.

Thanks for the help, that solved my issue.

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

Hi, I hope it’s ok to reply while the thread is already markes as solves.

I’m having the exact same problem with Zeal and GoldenDict on my two machines. Both qt5 applications crash for me with a similar invalid pointer error, either when I start them or shortly after, and the gdb logs look pretty much the same to me at first glance. Well, to be honest, I found it hard to follow this thread, since I have no experience in reading debug logs…

How exactly did you solve the problem, did you just install Java JDK 9 and set it as active via archlinux-java? At least that’s what I tried, but it didn’t do anything for me.

And does anyone know what even caused that problem? What does java even has to with this, at least Zeal and GoldenDict have nothing to do with java whatsoever.

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

I encountered with the same problem(java-9 activated, mendeleydesktop invalid pointer), but I can't find the solution from above replies. Can anyone clarify the solution again?
change active java environment to java-8 via archlinux-java? or set env QTWEBKIT_PLUGIN_PATH?

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

Hello, same problem, can't also understand how to fix it. I've created another thread in hope for more clear explanation: https://bbs.archlinux.org/viewtopic.php?id=231552

Edit: you have to forcefully delete jdk9 and leave only jdk8-openjdk.

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

I'm the maintainer of jdk/jre/etc. Tried exporting/prefixing QTWEBKIT_PLUGIN_PATH for the reader app Zeal, but didn't make a difference.

Solutions seem to be 1)

[downgrade] qt5-webkit (5.212.0alpha2-5 => 5.8.0-3)

2) OR remove the symlink: /usr/lib/mozilla/plugins/libnpjp2-jdk9.so → /usr/lib/jvm/java-9-jdk/lib/libnpjp2.so, if you're not gonna use the browser plugin anyway. Changing the default Java with archlinux-java isn't gonna make a difference.

This is not a fix and *will* break your system sooner or later

Re: [SOLVED] Error in/invalid pointer with numerous Qt applications

Hi, I fixed Zeal and GoldenDict by setting java-8-openjdk as my active Java environment and removing all other Java versions (Oracle/Open)
