Hi,

 

I just noticed that elf_open in tcf_elf.c sometimes throws exceptions. To me this is unexcepted. The function elf_open is not documented to throw exceptions. It is documented to return NULL on failure. The reason it throws is that it calls create_elf_cache, which calls create_symbol_names_hash, which calls unpack_elf_symbol_info, which throws exceptions. It is documented that unpack_elf_symbol_info throws exception.

 

I think this is a bug, but perhaps it is just a bug in the documentation for elf_open. What do you think?

 

Regards,

Anders
