[Bug c++/8966] [Alpha OSF5.1] Lost exceptions across library boundaries

It seems that this bug still applies as of g++-4.3, at least with optimizations
turned on. We're seeing this as we run the test suite of PPL (see, e.g.,
https://buildd.debian.org/fetch.cgi?pkg=ppl&arch=alpha&ver=0.10-4&stamp=1235334555&file=log&as=raw).
The code even has catch (...), but exceptions still propagate to the top.
Reproducible at any time, but I'm afraid we don't have small examples here
either.

Best,
Michael

Perhaps the PPL instance of this problem will be fixed with the switch to
strcmp for typeinfo comparison in 4.5.

I have tried to reproduce the problem with g++ 4.5 and couldn't make it fail
anymore. The problem, however, is that I couldn't make it fail with g++ 4.4
either. Whatever the essential change might have been, the PPL instance of this
problem seems to be fixed.

Best,
Michael

At this point, I think we can safely close this as fixed in 4.5.

I'm seeing some similar problems with gcc-3.4 and gcc-3.3.3 on i386-Linux. I've
got a routine throwing exceptions. In a simple testcase they get caught fine,
but in my program with the same code the exception just falls through and causes
a core dump. It's very hard to make a compilable testcase, but I've seen it in
two independent bits of code.

Does OSF support weak symbols and dwarf-2 exceptions.

The almost sounds like the typeinfo is not the same in both shared libraries when they are loaded 
which is needed for exceptions to work.
