This error occurs while compiling the function __muldi3 in the file
libgcc2.c.  You should be able to recreate the problem using the
command line which appears in your make log.  Use the --save-temps
option to get the preprocessed file (libgcc2.i).  That is a test case
for your compiler crash.  Figure out why the compiler is crashing, and
fix it.
