Fix crash when disassembling non-ELF files #259

Closed mtvec closed 3 years ago

mtvec commented 3 years ago

The return value of get_elf_backend_data was used without checking for NULL. Since this function seems to return NULL for non-ELF files, it caused a crash when disassembling binary files. This commit adds a NULL-check to fix this.

Patches must go upstream, and you must have an FSF copyright assignment in order for us to accept patches unless the patch is trivial. Or you can submit a bug report, and let someone with an assignment write the patch. See sourceware.org/binutils.

Already include this on upstream.
