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 Russ "Peter Dimov" <pdimov@mmltd.net> wrote in message news:002301c2d42c$dd99f820$1d00a8c0@pdimov2...

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.
You need -mthreads.
