[LLVMdev] php crash

[Anders Johnsen]

Hi,

I downloaded the file here, and used the same commands.

This is what I got:

Number of tests : 9537              5371
Tests skipped   : 4166 ( 43.7%) --------
Tests warned    :    0 (  0.0%) (  0.0%)
Tests failed    :    7 (  0.1%) (  0.1%)
Expected fail   :    3 (  0.0%) (  0.1%)
Tests passed    : 5361 ( 56.2%) ( 99.8%)

I'm on linux x86_64 with clang version: "clang version 1.0
(http://llvm.org/svn/llvm-project/cfe/trunk 68002M)". Not sure why
it's working here...
