Description Pétur Runólfsson 2003-01-20 09:56:00 UTC 
Exception handling in the formatted I/O functions (istream::operator>> and ostream::operator<<) appears to be broken.

1. Exceptions derived from std::exception are handled correctly, except that the original exception isn't rethrown if badbit is set in exceptions(), an ios_base::failure is thrown instead.

2. Exceptions not derived from std::exception are not handled at all, badbit is not set in rdstate() and the exception is passed on to the caller even if badbit is not set in exceptions().

Release:
gcc-3.2.1

Environment:
Red Hat Linux 8.0

How-To-Repeat:
See attachment.
Comment 1 Pétur Runólfsson 2003-07-02 15:49:42 UTC 
It seems this bug has been fixed, at least the test case now runs as expected.
Comment 2 Andrew Pinski 2003-08-07 13:10:50 UTC 
All tests pass on the mainline so closing as fixed.
