It's worth checking in case you are throwing exceptions accross shared 
library boundaries. I had a similar problem with GCC. Everything worked 
fine under gcc 4.5.2 (ubuntu) but not under the version of gcc that is 
default in CentoOS.  I discovered that it was an exception being thrown in 
a shared library ( and defined in the shared llibrary) that I was trying 
to catch in my executable.

I reolved it by moving all my exception definitions into a seperate shared 
library and linking it to all my other units including the main 
executable.

So to clarify, if all your execeptions are defined & implemented in a 
header file that you are including seperately in your shared library and 
your executable, but you are throwing and catching acrross the boundary 
you may see this problem. You need to compile the exception 
implementations into a shared library of their own and link it in to 
whereever you may thorw or catch them.

Can you run under GDB and see where the fault occurs?
