input files which raise OOM error in objdump

I tested objdump in binutils-2.32 with some fuzzed samples.

These samples have objdump raise out of memory error.

Error message is as follows:

~$ objdump -x ./crashes/id\:000000\,sig\:06\,src\:000008\,op\:havoc\,rep\:8

./new-test/crashes/id:000000,sig:06,src:000008,op:havoc,rep:8:     file format
