Bug ID: 19401
Summary: clang-compiled gcc has reproducible internal compiler
error
Product: new-bugs
Version: trunk
Hardware: All
OS: NetBSD
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: [email protected]

Classification: Unclassified
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
http://gnats.netbsd.org/48731
but the same problem also happened with pcre.
This problem was then reported upstream to gcc
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60807
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.
