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.
