What makes things worse about this workaround is that even protecting this by a #if defined(__GNUC__) may not be sufficient as other compilers may claim GNUC compatibility and behave differently. This is the case of clang (at least under Debian): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=705583 The only good solution would be to fix the bug. I've checked that it is still there in the trunk revision 197260 (current Debian's gcc-snapshot).
