It's the file in the libgcc source where the `new' operator is
implemented.  You can get it from the gcc281s.zip package, but it's
really not interesting; all it does is call `malloc', as you can see.

Your bug is probably corrupting the heap, which makes `malloc' crash;
check for pointer overruns and such.
