Description Louis-Dominique Dubeau 2001-05-15 17:43:53 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2-ldd i686; en-US; 0.7)

Description of problem:
Calling throw inside of a custom C++ terminate handler (set using
set_terminate) generates a call to terminate right away.  try-catch blocks
seem to be ignored.

How reproducible:

Steps to Reproduce:
1. Create minimal.cc containing:

#include <string>
#include <exception>

void my_terminate()
    cout << "in terminate" << endl;
    catch (...)
	cout << "caught" << endl;

main(int argc, char *argv[])

    throw exception();

2. make minimal

3. ./minimal

Actual Results:
in terminate
in terminate
in terminate
in terminate
[This is repeated until the program crashes.  A stack trace shows that
my_terminate is being called recursively.]

Expected Results:
in terminate
[program stops here]

Additional info:

Important note: on RedHat 6.1, compiling and running the above program
generates the expected results!

FWIW, this problem is fixed in gcc 3.0
