Hi, I was previously using the threading library with MinGW (latest release version) with no problems. Yesterday I came across a segfault that occurred when accessing a shared pointer so I updated the boost-cvs version I was using to see if it was a known problem that had been fixed; however when attempting to build the new version it appeared that threading had been disabled for MinGW? Is this the case or is it a problem with the way I'm building my code. Any help greatly appreciated, Russ

You need -mthreads.
Thanks, I found this after posting; unfortunately the segv still occurs as
it did
in the previous version (attempting the InterlockedExchange on a lightweight
mutex when adding a reference to a shared pointer). I'll check if i'm doing
anything else un-cunning.
Thanks again

No, threading hasn't been disabled for MinGW, and in fact I test with the Cygwin compiler using the -mnocygwin option, which should be equivalent to using MinGW. We'll need more information to figure out why it's not working for you. -- William E. Kempf
