Details
The problem occurs since last reboot so I guess it's a
kernel problem.
Name : linux Version : 3.17.3-1 Name : gcc-multilib Version : 4.9.2-1 Name : gdb Version : 7.8.1-1 Name : glibc Version : 2.20-3 When I run cppcheck with --exception-handling and make it crash, it just prints zsh: segmentation fault (core dumped) gdb didn't put out anything useful (yes, I compiled cppcheck with -g) eading symbols from /home/matthias/vcs/github/cppcheck/cppcheck...sdone. (gdb) start gcc/testsuite/g++.old-deja/g++.pt/ttp23.C Temporary breakpoint 1 at 0x68f42f: file cli/main.cpp, line 120.

Backtrace were fine before last reboot. |
