[This is Debian bug report #210848]

Somewhere between 2003-08-31 and 2003-09-08 on the GCC 3.3 branch, the attached
testcase began compiling to an infinite loop.  The loop is introduced between
00.rtl and 01.sibling so I suspect the CFG patches.  A jump is redirected to the
wrong label.

Can't test on mainline so I'm not sure if it's there too:

drow@nevyn:~/qter/test% /big/fsf/obj-i686-linux/gcc/cc1plus -O0 -finline -o
test33.s test.cpp
cc1plus: internal compiler error: in common_handle_option, at opts.c:655

Most likely the same as bug 12223.
