Hello all,
I can confirm this bug on gcc 3.2.3 compiler. Removing the flag -milp32
allows the testcase to compile successfully. Attached is a distilled
testcase from unwind-ia64.c which crashes the compilers (taken from a
cross build). With 3.3 cvs we crash at a different point, no matter
what flags are used, and with mainline at a still different point also
independent of flag. Yuck. Testcases follow.
