[llvm-commits] CVS: llvm/lib/Support/LeakDetector.cpp

[Chris Lattner]

Changes in directory llvm/lib/Support:

LeakDetector.cpp updated: 1.7 -> 1.8

---
Log message:

Fix a bug in the recent rewrite of the leakdetector that caused all of the 
nightly tests to be really messed up.  The problem was that the new leakdetector
was depending on undefined behavior: the order of destruction of static objects.

Diffs of the changes:  (+10 -7)
