Hello,

As I see in my x86_64/linux gcc build and for example recently in:
http://gcc.gnu.org/ml/gcc-testresults/2012-02/msg02269.html

=== boehm-gc tests ===
Running target unix/-m32
FAIL: boehm-gc.c/thread_leak_test.c -O2 (test for excess errors)
=== boehm-gc Summary for unix/-m32 ===
Running target unix
FAIL: boehm-gc.c/thread_leak_test.c -O2 (test for excess errors)

due to redefinition of GC_LINUX_THREADS.

Any reason why this patch was not applied?

Thanks!

Also note that the trunk boehm-gc seems to be fixed like this:

Patrick, This form still randomly fails on x86_64-apple-darwin11 with the logged output of...

This is another problem (related to darwin) as discussed in PR48299.
You should try the bdwgc trunk (https://github.com/ivmai/bdwgc/) and see if the test passes. It could give a indication if it is still an unsolved issue or not.


Patrick.
