A 64 bit build of gcc 4.4.2 installed via darwinports on a Mac Pro server
running Snow Leopard 10.6.2 causes a crash in the following program:
>cat src/test.cpp
#include <iostream>
struct X
{
~X () // crash disappears if there is no destructor
{
}
};
void
dummy ()
{
X x;
throw 0;
}
int main()
{
try
{
dummy ();
}
catch (...)
{
std::cout << "CAUGHT" << std::endl;
}
return 0;
}
Instead of the expected "CAUGHT" the system pops up with:
Exception Type: EXC_CRASH (SIGABRT)

As long as a local object 'x' with a destructor is created prior to the 'throw'
inside dummy(), the problem occurs.
