I'm now regression testing what I think is a fix, but it would be very helpful if you could come up with a testcase that I could check in to CVS (or even just one that I could run). Otherwise I have no way to know if I've fixed the problem you saw. The original report provides GDB output, but no source files or command lines that I could use to reproduce that output. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13689
