Hi,

when running our c++ application on Intel's Xeon 5570 processors with the latest Solaris 10 Update 7 (141415-10), we're having problems with exceptions not being caught properly when running 64bit processes. After some analysis, it seems that if an exception is thrown in a shared library "B" which was loaded through dlopen() and has its exception handler in its parent library "A", the exception handler is sometimes "ignored" (not found on the stack or whatever...), so the exception runs "all the way through" and causes the process to crash due to an uncaught exception.
What kind of exception?  There are exceptions that cannot be caught.
We should rule out this possibility when running your code on x64.
