           Summary: Assertion failed when parsing inline asm arguments
           Product: clang
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal

Test case

Clang was built from SVN revision 128339.
Tested on Mac OS X 10.6.

If I try to compile the attached test case using "clang -c -o asmbug.o
asmbug.cpp", an assertion triggers:
Assertion failed: (0 && "Unknown builtin type!"), function getTypeInfo, file
/Users/mth/src/llvm/tools/clang/lib/AST/ASTContext.cpp, line 740.

The test case is a minimized version of an actual program that triggered this
assert. For some reason, the presence of the template and the offset for "out"
(even if it is 0) are essential to trigger it.
