Any difference between gcc 4.3 and 4.1 in exception handling?

[jacob navia]

I would like to know if the exception handling software has changed 
between 4.1 and 4.3.

I have developed a module to generate gcc compatible dwarf debug info
and it works with gcc 4.1. It is in the context of a JIT.
Now I have some mysterious crashes with gcc 4.3 under Suse 11.
Ubuntu seems to work...

Thanks in advance for any info.
