Exception thrown from multithreaded shared lib not caught in main

[Martin York]

void Lixo::lib_func() throw()
{
    throw Lixo::ValidationException("Hello!");
}

The above code, will result in a call to std::unexpected() and thus to std::terminare() and from there abort() resulting in the application exiting without the stack unwinding to main().

By specifying that the method 'lib_func()' throws nothing 'throw()' any thrown exception (because they are all unexpected) should generate a call to std::unexpected().




Martin.

Hello again,

Following my previously presented problem, I have built an example that replicates the problem:

http://jpinto.homeip.net/~jpinto/lixo-0.1.0.tar.gz

Just run ./configure && make check

It builds a shared library with a function that throws an exception, and an executable that calls the library function. Aparently multi-threading is not the issue. The problem is that the exception is never caught in main(), and unhandled() gets called.

Tested with g++-3.3.4 and g++-3.4.2 (Debian testing x86).

Thank you for your time.

João Luis
