sre in 2.3x is compiler sensitive - the stack frame size becomes critical
in how many sre recursions are supported, and a core dump is certain if
the sre recursion limit is more than the available stack space allows.
Threads support may be mixed in with this, as the size of the stack for
the primary or initial thread is what gets exercised by test_re.
On FreeBSD 4.x the stack size for this thread is fixed at 1MB (pthreads
implementation limitation, not OS limit). gcc versions < 3.0 don't cause
problems with the default sre recursion limit of 10000, but later
So I'd suggest trying a lower sre recursion limit to see whether this
