            Bug ID: 15290
           Summary: Segmentation fault during template instantiation
           Product: clang
           Version: 3.2
          Hardware: PC
                OS: other
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: C++11

Reduced code triggering segmentation fault.

When invoking (using attached fail.ii):

/usr/bin/clang-3.3 -cc1 -triple amd64-unknown-bitrig0.1 -emit-obj -std=c++11 -x
c++ -o /dev/null fail.ii

the compiler fails with:

Stack dump:
0.      Program arguments: /usr/bin/clang-3.3 -cc1 -triple
amd64-unknown-bitrig0.1 -emit-obj -std=c++11 -x c++ -o /dev/null fail.ii 
1.      <eof> parser at end of file
2.      fail.ii:55:2: instantiating function definition '~refpointer'
3.      fail.ii:41:2: instantiating function definition 'release'
Segmentation fault (core dumped)


The code has been reduced, so the compiler will spew a couple of errors.

I had the error first on maxosx, but reproduced it on bitrig (a fork of
openbsd).  The llvm-3.3 I'm using is was compiled at Dec 3.  For macosx, I
first found the error in their 3.2svn version, another maxosx with a 3.1svn
reproduced this; the previous compiler which was also based on 3.1 did not have
this problem, leading me to believe it was introduced somewhere between 3.1 and
3.2 release.
