Extended Description

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.

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

Indeed fixed by r146950.

This bug has been marked as a duplicate of bug llvm/llvm-project#11943

efriedma-quic commented 12 years ago

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

efriedma-quic commented 12 years ago

Looks like this is related to bug 11571.
