libthr or libgthread (devel/glib20) bug?

[Jeremy Messenger]

Any apps that are depending on libgthread-2.0.so.200 always will crash if 
it's linking to libthr (using libmap.conf). My previous email about gst- 
register, it will not crash anymore if I set libgthread links to libc_r 
instead libthr. All ports that I have installed have been compiled with the 
debug (-g). Anyway, here's gdb info of ggv:

Here's gthread-posix.c source codes look like.. I don't know if it helps, 
but at least I am trying..
