[SOLVED] GDB freezes computer with multithreaded program

I'm working on https://github.com/Fluorohydride/ygopro. I'm using eclipse on a fully updated system (linux-lts 3.14). During debug when I step over or step in, whole system freezes. I've to power off the system. This behavior is random, like it may happen after 10 step overs or 18 , sometimes it happens with just 4 step over. Netbeans was also showing the same behavior. I don't know which log to provide. Please help.

Make sure your system is up to date. A few month back gdb had similar problem https://sourceware.org/bugzilla/show_bug.cgi?id=17247

If updated system still shows the same issue then run another gdb attach to the hang gdb process and print its stack.

GDB hangs whole computer. I'm just able to move mouse and nothing else works.

Re: [SOLVED] GDB freezes computer with multithreaded program

If you're able to move the mouse [pointer], it seems unlikely that the "whole computer" is hanging. You could try Ctrl+Alt+Bksp to kill X, but I think that feature needs to be enabled with an X config file these days. You could also try switching to a TTY, or if practical set up sshd and try connecting from another machine. If all else fails, try REISUB.

I've amd graphic card, so I was using proprietary driver. Last night I switched to open source drive, since then I'm not getting that hanging issue. But open source driver performance is visibly slow.
