--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> 2010-11-02 21:07:44 UTC --- Created attachment 22241 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22241 A testcase This isn't the correct C++ code. But the crash is similar: (gdb) r -fpreprocessed pr46277.ii -quiet -dumpbase pr46277.ii -mtune=generic -arch=x86-64 -auxbase pr46277 -O2 -version -o pr46277.s Starting program:
