Eli,
Our GDB is configured as "--host=i686-mingw32 
--target=i686-pc-linux-gnu", instead of native mingw32 gdb.

(gdb) gcore
Saved corefile core.2493

So gcore works, and sorry for the confusion.

I checked the log today again, and find the compilation is failed 
because of the too-long file name, I think.
