ARM cmse_scan segfault
This code in elf_link_add_object_symbols:
ret = elf_add_dt_needed_tag (abfd, info, soname, add_needed);
if (ret < 0)
goto error_return;
/* If we have already included this dynamic object in the
link, just ignore it. There is no reason to include a
particular dynamic object more than once. */
if (ret > 0)
return TRUE;
prevents a shared library from being loaded twice by ensuring that any
library soname doesn't match the soname of one already loaded. This
happens before sym_hashes are allocated, which leaves sym_hashes NULL.
cmse_scan looks at library symbols, and when attempting to look up a
global symbol will segfault if sym_hashes is zero.
* elf32-arm.c (elf32_arm_size_stubs): Exclude dynamic library
BFDs that have not been loaded.
