Description Alexander Larsson 2000-11-17 05:34:22 EST
Ok, here is a new -finstrument functions bug. It might be connected to my
previous one 20952, but this one gives an ICE while compiling instead of
generating bad code.

gcc -O2  -finstrument-functions pixops_pre.c 
pixops.c: In function `bilinear_quadrant':
pixops.c:1255: Internal compiler error in change_stack, at reg-stack.c:2214
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

At -O it does not crash.

Testcase commited to gcc CVS as gcc.dg/20001117-1.c, no fix yet.
Comment 3 Jakub Jelinek 2001-03-14 11:23:05 EST
I have fixed this in my tree, am just bootstrapping CVS gcc with it before
submitting it to gcc-patches. It will appear later on in gcc-2.96-79.
