      Qt Creator crashes when I edit pri file, save it and then start qmake fast (using shortcut), or even if it started automatically after saving.

      gdb log is in attach.

      Unfortunately I can't attach core file, because can't create it ("ulimit -c unlimited" does not work, generate-core-file in gdb-7.5 shows "Couldn't get registers: No such process."). Also I tried to use valgrind to find memory error, but no success.

      This bug can't be reproduced on very little project, so can't send one. I can send my project by e-mail, if you need to reproduce that bug.
