Segmentation fault while using apr thread pool

[Abhi Auradkar <aurabhi@xxxxxxxxx>]

Hi All, 

  I am facing a problem while using the apr thread pool.

I see a core dump intermittently. This is what the output looks with dbx. 

t@null (l@53) terminated by signal SEGV (no mapping at the fault address)

0x7fb7a948: add_if_empty+0x010c:        st       %i1, [%l2]

Any help help will be really appreciated.
