>Description:
gcc dies with SIGSEGV when compiling the attached file with -mcpu=ultrasparc.
>How-To-Repeat:
$ gcc -mcpu=ultrasparc -c foo.c -o foo.o
gcc: Internal compiler error: program cc1 got fatal signal 11
>Fix:
Rewriting the subtraction as:
stack_top -= lim.rlim_cur;
seems to work around the bug.
