Comment on attachment 4096 [details] test stupid IE.
Created attachment 4099 [details] testcase Hopefully Netscape 4.7 is better than IE for the Mac.

Created attachment 4101 [details] reduced testcase
I have attached the reduced testcase. It's not a regression since it ICEs GCC since at least 2.95.
Actually this code is invalid because it jumps out of a Statement expression but it still ICE even after changing the Statement expression to just a statement on the mainline (20030711) so it still is a bug.
Only fails at -O1.
