------- Comment #5 from jbuck at gcc dot gnu dot org 2007-01-14 00:51 -------
I do not see this crash with gcc 4.1.1. Is it still present?
I did see it with 3.4.2.

-fstack-check doesn't work on Linux/x86 and Linux/x86-64 without runtime
support.
Only the Ada compiler currently implements it.

(probe_stack_range): Use Pmode and memory_address consistently. Fix
loop condition in the small constant case. Rewrite in the general
case to be immune to wraparounds. Make sure the address of probes
is valid. Try to use [base + disp] addressing mode if possible.

checking is enabled and STACK_CHECK_MOVING_SP.
* rtlanal.c (may_trap_p_1) <MEM>: If stack checking is enabled,
