We actually did use gcc 2.95.2 with the stlport library because we knew
that we would be using this on a multi-processor machine.

Another thing.  Which compiler and STL implementation
are you using?  We know that there are bugs in the gcc
STL implementation for gcc 2.95.x, when using strings
on a multi-processor machine.  This causes random bad
behavior.  For these cases we recommend using STLport.
