I had to write a patch for that. The patch can be found here: http://gcc.gnu.org/ml/gcc-patches/2004-04/msg01328.html With this patch applied, the testcase compiles OK. So it looks like we need to backport this patch onto the gcc-3.4 branch. I am leaving for the GCC Summit tomorrow, so I won't be able to test this until next week. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15569
