Memory leak in disassemble_init_for_target

[Philippe Antoine]

Hi everyone,

My name is Philippe Antoine
I have been fuzzing binutils disassembler.
And I would like to report two bugs, and propose the fuzz target.
This first mail is for the first one.

This is a memory leak in function disassemble_init_for_target
Binutils version is from commit d8f68fcb9378b5ab1c945fa676e11da15be56dd6
disassemble_init_for_target calls cgen_bitset_create for certain architectures 
: bfd_arch_m32c and bfd_arch_bpf
And is seems to me that this ressource gets never freed (in programs such as 
objdump) (or am I missing a clean function to be called ?)

Best regards,
Philippe
