" Using fork() alone executes correctly. Only when using exec* or posix_spawn* generates the issue. Attempting this on the following platform OS: Debian Squeeze (Linux 2.6.32-5-amd64) GDB version 7.3 (Debian Backport) I am using Eclipse CDT IDE to interact with GDB and attached is the GDB Trace. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread

That said, I've tried it myself, on the command line, with: $ gdb -i=mi pr6998 -ex "set target-async on" -ex "set non-stop on" -ex "set detach-on-fork off" both mainline and 7.6, and I saw no crash. Please reopen if you can reproduce this with 7.6 or mainline.
