Try to reproduce segfault.

Link to gdb simple howto.
http://www.midgard-project.org/community/development/debugging.html



After back to 2.4.27 kernel, load a gdb compiled Apache, gdb says:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 16384 (LWP 1201)]
0x40235ede in mallopt () from /lib/libc.so.6



After upgraded libc6, recompile Midgard I got:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 16384 (LWP 19589)]
0x40235fb1 in _int_malloc () from /lib/libc.so.6

With apache 1.3.33, PHP 4.3.4, Midgard 1.6.3, OpenSSL 0.9.7c, mod_perl 1.29


...with the backtrace:

Program received signal SIGSEGV, Segmentation fault.
