Exception handler of RHEL4 isn't working after the integration ofboost Serialization code

[girish574]

After the integration of boost serialization code, the exceptions
are not at all getting caught in my application. Im building on RHEL4
kernel 2.6.9-42.ELsmp and gcc version is 4.0.2. The application
terminates when exception is thrown. Removing the serialization code
makes the exceptions getting caught.

The worst part is im not able to reproduce the scenario in a small
program.
Also i tried building the same application on suse8 machine. Even
with the boost serialization code exceptions are getting caught. Issue
is there only with RHEL4 build

Do anyone of you encountered this? Or can you point to any potential
mistake for which this can happen?
Is there any gcc flag that may help in this issue
Thank You

One thought.

After an exception is thrown the stack is unwound.
During the unwinding the destructor of all stack objects is called.
If one of the destructors of these objects also throws an exception
then the application will terminate.

struct X
{
~X() {throw int(5);}
};

int main()
{
try
{
X a;
throw int(6);
}
catch(int e)
{
std::cout << "Cought\n"; // Never gets here.
}
std::cout << "Done\n";
}

Im having a simple scenario in my application
int x = 6;
try {
throw x;
}
catch(int p) {
cout << caught << endl;
}
This is not getting caught on RHEL4 + boost. But it does on suse8 +
boost

Sounds implementation specific. I suggest either an RHEL group, the
BOOST mailing list, or gnu.g++.help
