Subject: [boost] [thread] Memory usage of threads on 64bit linux

Hey,
I have been using boost threads on 32bit linux for some time and am very
happy with their performance so far. Recently the project was moved to a
64bit platform and we saw a huge increase in memory usage (from about
2.5gb to 16-17gb). I have done profiling and found that the boost
threads are the source of the huge allocation. Each thread is allocating
about 10x what it was doing on 32bit.
I profiled using valgrind's massif and have confirmed the issue using
only boost threads in a separate test application. I also tried using
std::threads instead and these do not exhibit the large memory
allocation issue.
I am wondering if anyone else has seen this behaviour and knows what the
problem is?
Thanks
