Re: [Boost-users] the thread safe boost serialization library is threadsafe?

It has been determined that the boost serialization - contrary to intention - is not currently thread safe. This will be addressed in a future release. Robert Ramey Fei Liu wrote:

I am testing a multi-thread app which uses boost serialization library..I got the dreaded error: *** glibc detected *** double free or corruption (fasttop): 0x0aed93d0 *** Aborted

Using a core dump and gdb, here is a backtrace. It appears it crashed inside the multi-thread library. Any advice is appreciated..
