[Libmesh-devel] Mutex lock-up when using periodic boundary conditions in debug mode

[David A. <Dav...@in...>]

Hi!

I think I found a bug when I was working on the periodic-boundary patch 
(submitted earlier today). If I compiled libmesh in debug mode and ran my 
application, it locked up. I figured out that point_locator() is called 
(mesh_base.C line 287), it allocated a mutex and then it called a 
constructor for PointLocatorBase::build() created object. Since 
PointLocatorBase inherits from ReferenceCountedObject, the 
increment_constructor_count was called (reference_counter.h, line 167) and 
it tried to allocated the same mutex there again. Everything works fine in 
OPT mode, since the body of increment_constructor_count is empty.

Could anyone verify this? 

Thanks,
