Rich -

I'm not 100% sure its fixed - I'm still seeing "out of memory" errors when running about 40 prob imb over openib. But I ran out of time to investigate deeply...

Could you try running a nontrivial omb to check?

R16641 should have fixed the regression. Anyone using ompi_free_list_t_ex()
and providing
 a memory allocator would have been bitten by this, since I did not update
this function
 (which will be deprecated in favor of a version parallel to
ompi_free_list_t_new) to initialize
 the new fields defined. From looking through the btls, this seems to be
only the openib btl.
