Yes, that's known problem at this time.

GNU/Libc based backtrace() stacktrace capturing is causing deadlocks.

Please use libunwind until this is fixed.

My work here: https://github.com/alk/gperftools/tree/wip-emergency-malloc 
already passes unit tests and should work on GNU/Linux.

Some other OSes as well as more testing is still pending.

Still observed deadlocks while running tcmalloc tests on mips64 platform.

Using latest gperftools-2.2 sources.

And also observed stacktrace compilation issues with latest gperftools-2.2 on 
mips64 platform

Please open separate ticket(s) for mips64. With details please.

And don't expect anything beyond --enable-minimal (just malloc) to work on mips 
at this time.
