XCode 4.4 harmful

[Jeremy Sequoia]

Please definitely file a bug report at http://bugreport.apple.com

The most likely culprit as to what changed is the compiler.  Can you try using configure.compiler=macports-clang-3.1 (and 3.0 and 3.2) to see how they fare.


Do you know specifically which library / executable is broken?

James has determined that code produced with XCode 4.3.3 works OK; XCode 4.4.0+ leads to crashes.  Testing done on 10.7.4.
