           Summary: regression in trunk...failing make check
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

So I am in the process of narrowing down where this occurred and I am a
software engineer that would loved to get involved in the clang project so I
may be able to come up with a fix or patch.

I had no problems compiling/testing llvm by itself (check, not check-all) with
gcc 4.1.2 which I understand is not supported. I began to have some issues with
clang so I decided to grab all updates from llvm and clang out of trunk and
recompile. The problem was still there so I grabbed the gcc44/g++44 packages
from CentOS5 yum repo. This is gcc 4.4.4. Still had problems. 4.4.4 _is_
supported so at this point I started going back to find where this regression

Revision#131480 fails ## tests (using GCC 4.1.2/4.4.4)

Revision#131450 passes all (using GCC 4.1.2/4.4.4)

I will try to narrow this down to a specific revision, look at the diffs, and
see whats going on. I suspect that either a bug was not being tested on and
therefore I should not be passing, or that a regression has entered trunk
between 131450 and 131480. As 4.4.4 is supported, I could understand 4.1.2 not
passing tests if a bug was missed but 4.4.4 should be able to pass without

Hopefully more later today.
