 I am getting the following assertion failed

 /usr/local/include/boost/interprocess/sync/posix/interprocess_recursive_mutex.hpp:107:
 void boost::interprocess::interprocess_recursive_mutex::unlock():
 Assertion `res == 0' failed.

 when compiling the extremely simple attached program in GCC 4.4.3 with
 optimization on (-O2 or -O3)

 it doesn't happen with -O0 or -O1, or if I use -fno-strict-aliasing on top
 of -O2.

 I have also got this assertion failed error with GCC 4.4.1, but I wasn't
 able to isolate it into a simple program.

 The bug depends a lot on the GCC version and the optimization options, so
 I guess it is a bug in the compiler, but it affects the usability of
 boost, so I think it is worth reporting it here
