Running inside the gdb worked. Seems like a problem with libmpfr. Will try
compiling it from source.
Following is the end of the GDB output:
/export/home/amandeep/gccgo-src/libgo/go/fmt/scan.go:658:43: error:

s.errorString("integer overflow on token " + tok)

/export/home/amandeep/gccgo-src/libgo/go/fmt/scan.go:688:52: error:

s.errorString("unsigned integer overflow on token " + tok)
^
