When compiling the attached C code with optimisation, I get an ICE:

Comment 2 Volker Reichelt 2004-03-05 10:36:06 UTC
Reduced testcase that segfaults when compiled with "-O2 -march=i686"

int i;

void foo(int *p)
  if (*p) i=1;
Comment 3 Andrew Pinski 2004-03-05 15:19:54 UTC
This is almost definitely a RTL problem.
Comment 4 Volker Reichelt 2004-03-12 09:36:28 UTC
The problem disappeared today.
