I have a C++ application compiled using gcc 2.95.2

I experience weird and not 100% repeatable mis-behaviour of
the application which is hogging all CPU-time.
(some threads are SCHED_RR)
Which leads me to the question:
Was the C++ Exception Handling thread-safe in gcc 2.95.2.
Based on the result of our configuration test I would have
to say no. Try it and see: http://tinyurl.com/yl5dxw.

I wonder because gcc-2.95.2/gcc/except.c tells:
The mechanism in C++ for handling data associated with the
exception is clearly not thread-safe. For a thread-based
environment, another mechanism must be used (possibly using a
per-thread allocation mechanism if the size of the area that needs
to be allocated isn't known at compile time.)
Whereas
gcc-4.1.1/gcc/except.c does not.
I know there are MANY gcc release between those two but I would be glad
if any GCC historian may tell me what was the first C++ EH thread-safe
version of gcc?
