Marking this bug invalid - the code in question turned out to have a GC that
did not correctly support IA64's RSE. With optimization, stuff was getting
hidden from the GC in the RSE backing store and incorr

Actually, I shouldn't have closed this so hastily. The code _is_ pretty dirty
but I'm not sure GCC is really doing something legal at -O2.

oops, my mistake. this bug appears on x86 too, at least:
gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-13)
fails (at -O2), but:
gcc version 3.3.6 (Debian 1:3.3.6-3)
works. Perhaps this is a bug
