        <pre>I'm using clang coming with NetBSD, on NetBSD-6.99.40/amd64, currently:

clang version 3.5 (trunk 202566)
Target: x86_64--netbsd
Thread model: posix

NetBSD also comes with a version of gcc:

gcc (NetBSD nb2 20140304) 4.8.3

When using that clang to compile that version of gcc and then use gcc to
compile software, a reproducible internal compiler error appears that does not
happen when gcc is compiled with gcc.

The original bug report was filed for a compilation problem with gambatte, see

<a href="http://gnats.netbsd.org/48731">http://gnats.netbsd.org/48731</a>

but the same problem also happened with pcre.

This problem was then reported upstream to gcc

<a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60807">http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60807</a>

until it was found that this only happens when gcc is compiled with clang.

This looks really hard to debug, but I wanted to report it anyway. Let me know
how to proceed.</pre>
