Do you have any further update here? From looking through the core file I am
not convinced that there is a lock order reversal between tcmalloc and pthread.

I think i'm having the same problem but it does not happen all the time. It's
hard to debug.
One thing though, it appears to only happen when doing a HEAPCHECK ... dunno if
it helps.

This is deadlock between libdl lock taken in dlopen and being waited for by
dl_iterate_phdr and tcmalloc spinlock.
Later versions of glibc fixed this by having separate lock that dl_iterate_phdr
take and that dlopen takes but very briefly.
My investigation of RHEL5 glibc shows that latest rhel5 releases _do have_ that
fix.
Setting to "cannot-reproduce" to indicate that issue is fixed but not by us.
Please reopen if RHEL 4.9 still causes same deadlock.
