icewm crashes upon startup after update

After the following recent updates:

    xorg-server-1.20.0-5-x86_64.pkg.tar.xz
    xorg-server-common-1.20.0-5-x86_64.pkg.tar.xz
    icewm-1.3.8-5-x86_64.pkg.tar.xz

icewm fails to start and the icewm process repeatedly segfaults with a core dump (possibly using all disk space when core dumps are enabled) until the X server is shutdown.

Here is the backtrace:

Core was generated by `icewm'.
Program terminated with signal SIGSEGV, Segmentation fault.

Re: icewm crashes upon startup after update

What package versions did you update from that were working?

Re: icewm crashes upon startup after update

I experienced the same thing in version 1.3.8-5, on 32-bit though.

Re: icewm crashes upon startup after update

20      void YPixmap::replicate(bool horiz, bool copyMask) {
(gdb) bt
#0  0x004c11a2 in YPixmap::replicate(bool, bool) (this=0x0, horiz=true, copyMask=true) at ypixmap.cc:20

this=0x0 doesn't sound good somehow..

Re: icewm crashes upon startup after update

Sounds like pixmaps are not found (or a X resource path not set)..

Re: icewm crashes upon startup after update

So, from debugging I can tell, icewm loads the pixmaps:

Breakpoint 1, YResourcePaths::loadPixmap (this=0x52dc70, base=..., name=...) at ypaths.cc:125
125     ref<YPixmap> YResourcePaths::loadPixmap(upath base, upath name) const {
1: name.fPath.fStr[0] = {fRefCount = 1, fStr = 0x524be4 "titleAB.xpm"}

and crashes afterswards.

Re: icewm crashes upon startup after update

Ah, patching null ref's in wmapp.cc helps. At least I get a working wm again.
I'll provide a patch upstream..

Perhaps consider switching to the fork https://github.com/bbidulock/icewm.
