solaris x86 exception handling bug

[dvermeir@tinf1.vub.ac.be]

Hello,

There is a bug in egcs-1.1.1 for Solaris x86: in some (very simple)
cases an exception thrown from a shared library is not caught.
I enclose a minimal demo program (bug.tar extracts to bug/*):
it works on solaris sparc but not on solaris x86.

Replacing the single ``string'' data member in the class
by e.g. an integer also makes the program work.

Otherwise, egcs-1.1.1 installed beautifully and I managed
to port all my C++ programs to the solaris x86 environment
without a problem. All programs use shared libraries, templates and
apart from exception handling, everything works fine.

If there is a known fix for this problem, I would greatly
appreciate if you could refer me to it.

Thank you for a wonderful compiler.

Best regards,

dirk vermeir
