bfd has several memory leaks. I'm fixing the ones in dwarf2.c, but a simple grep
for 'bfd_realloc' shows several obvious leaks on failure:
./bfd/bfdio.c: bim->buffer = bfd_realloc (bim->buffer, newsize);
./bfd/bfdio.c: bim->buffer = bfd_realloc (bim->buffer, newsize);
./bfd/bfdwin.c: i->data = bfd_realloc (i->data, size_to_alloc);
./bfd/elf-eh-frame.c: sec_info = bfd_realloc (sec_info,
./bfd/elf-strtab.c: tab->array = bfd_realloc (tab->array, tab->alloced *
amt);
./bfd/elf32-arm.c: map = bfd_realloc (map, mapcount * sizeof
(elf32_arm_section_map));
./bfd/elf32-ppc.c: contents = bfd_realloc (contents, trampoff);
./bfd/elf32-xtensa.c: message = (char *) bfd_realloc (message, len);
./bfd/elflink.c: finfo->symshndxbuf = destshndx = bfd_realloc
(destshndx, amt * 2);
./bfd/elfxx-ia64.c: contents = (bfd_byte *) bfd_realloc (contents,
amt);
./bfd/ihex.c: buf = bfd_realloc (buf, (bfd_size_type) chars);
./bfd/ihex.c: buf = bfd_realloc (buf, (bfd_size_type) len * 2);
./bfd/mach-o.c: buf = bfd_realloc (buf, size);
./bfd/stabs.c: symb = bfd_realloc (symb, buf_len);
./bfd/vms-misc.c: PRIV (vms_buf) = bfd_realloc (vms_buf,
./bfd/vms-tir.c: = bfd_realloc (PRIV (image_section)->contents, offset +
size);
./bfd/vms-tir.c: PRIV (sections) = bfd_realloc (PRIV (sections), amt);
./bfd/vms.c: PRIV (sections) = bfd_realloc (PRIV (sections), amt);
Hopefully at some point somebody can find time to carefully audit the whole
source base, these are just a few obvious leak points.
