Hi,

   There is currently a bug in the g++ 1.32 cplus-parse.y file.
It causes a segmentation fault with the following construct:

----------------------------------------
main () {
   int j = ({1;});
}
----------------------------------------

   I've found the problem with this, and included the patches
for cplus-parse.y below.

   Doug
