Following code generates Floating point exception:

echo $(( 2**63 % -1 ))

I don't have debug symbols installed at the moment, sorry.

Reading symbols from busybox...(no debugging symbols found)...done.
(gdb) run sh -c 'echo $(( 2**63 % -1 ))'
Starting program: /bin/busybox sh -c 'echo $(( 2**63 % -1 ))'

Program received signal SIGFPE, Arithmetic exception.
0x0000000000423b85 in ?? ()


This exception only appear on 64 bits apparently, tried on 32 bits but it
didn't occur.
