[Bug c++/38490] New: stack overflow with -O2 for legal C++ code

[dcb314 at hotmail dot com]

I just tried to compile the package Coin-2.5.0-1.pm.3
with the GNU C++ compiler version 4.4 snapshot 20081205.

The compiler said

g++: Internal error: Segmentation fault (program cc1plus)
Please submit a full bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.

The preprocessed source code is attached. Flag -O2 required.

Here is valgrind helping out with a stack backtrace

==3265== Stack overflow in thread 1: can't grow stack to 0x7FE801F98
==3265== Can't extend stack to 0x7FE8016A0 during signal delivery for thread 1:
