Hi all. Thanks for your work on LLVM and clang.

When I try to build Freecell Solver ( http://fc-solve.shlomifish.org/ ) using
it, I'm getting a segfault on one of its board generation programs:

I'll attach the offending file soon, and a reproducing script, and a patch I
applied to the clang svn trunk to get it to run properly on Mageia Linux.

Looks like this is related to bug 11571.

[Quuxplusone]

This should be fixed as of r146950; would you mind checking that?

[Quuxplusone]

Indeed fixed by r146950.

@Eli Friedman: it is indeed OK now after I did "svn up" and rebuilt.
