That means the filename is freed by _bfd_free_cached_info. Which is called by _bfd_compute_and_write_armap to tidy up symbol tables after they are done with. Unfortunately, _bfd_write_archive_contents wants to seek and read from archive elements after that point, and if the number of elements exceeds max_open_files in cache.c then some of those elements will have their files closed. To reopen, you need the filename. PR 25993 * opncls.c (_bfd_free_cached_info): Keep a copy of the bfd filename. (_bfd_delete_bfd): Free the copy. (_bfd_new_bfd): Free nbfd->memory on error. -- You are receiving this mail because: You are on the CC list for the bug.
