Extended Description

Good day,

While building cairo on: clang version 1.1 (trunk 84751)

We hit the following Assertion:

Are we falling off the end of a link list or something? Thanks for your time, Edward.

OK, I believe this was fixed in or around revision, 84801. I'll close this for now as it looks to be working.

Cheers, Edward.

MDNode::dropAllReferences() should be gone, is this fixed on mainline? :)

llvmbot commented 14 years ago

N.B. When attempting to build the code without the "-g" flag, things continue as they should..

Cheers, Edward.
