Tail recursion vs exceptions vs C++

[Iain McClatchie]

I cannot compile the following one-line program without
disabling exceptions.  Fails for both GCC 3.2.2 and 3.2.1.

int main() { main(); }

Use the command line:
gcc tail.cc

Note that if the C compiler is used rather than the C++
compiler, GCC succeeds.  egcs-2.91.66 (that's the old Red
Hat release) works, if that matters.
