[tao-users] Exceptions from TAO not being caught

[Heyman, R Gary]

Sending my question here because when I try to send to tao-bugs at list.isis.vanderbilt.equ<mailto:tao-bugs at list.isis.vanderbilt.equ>, (as per the instructions) it gets returned shortly with "This is a moderated mailing list".

    AREA/CLASS/EXAMPLE AFFECTED: -

    DOES THE PROBLEM AFFECT:
        COMPILATION?  No
        LINKING?  No
        EXECUTION?  Yes
        OTHER (please specify)?

    SYNOPSIS:
Running on Solaris, exceptions thrown from TAO code are not caught, and
program execution terminates.

    DESCRIPTION:
On Solaris, as soon as we started compiling with -std=c++14, exceptions thrown
from TAO cause program termination.  Exceptions thrown from TAO are not caught
as they were prior to using -std=c++14.

Notes:
Exceptions thrown in functions before calling TAO functions work as expected.

I added an catch block in the TAO function that throws an exception, and the
program still terminates.

If we compile without using -std=c++14, TAO throw exceptions work as expected,
this builds as __cplusplus = 199711.

We see the same TAO exception error if we build and run the TAO supplied
program(s) in TAO/examples/Simple/bank on Solaris.

On Linux, using g++ (GCC) 8.3.1 20190311 (Red Hat 8.3.1-3), compiled with
-std=c++14, TAO thrown exceptions work as expected, using the same TAO version
as Solaris, and using the same build command(s) the for ACE TAO code.

On Solaris and Linux, we are building 32-bit executables.

    REPEAT BY:
Just running our program that is using TAO code.

    SAMPLE FIX/WORKAROUND:
None.
