[Bug admin/3239] New: The "info" declared in the function _dl_start of the rtld.c is not initialized

cvs-commit at gcc dot gnu.org
My project is to load an ELF executable file by using dynamic loader ld.so.
After I mapped the executable and the loader in memory.  I start the loader
program. But, I got the error message as below,

Inconsistency detected by ld.so: rtld.c: 306: _dl_start_final: Assertion `info-
>l.l_tls_modid == 0' failed!

The info is declared in the function _dl_start. The info->l.l_tls_modid has
never been assigned to any value after that (USE_TLS is defined, USE_THREAD
and DONT_USE_BOOTSTRAP_MAP is not defined). When loader ran to line 306--assert
(info->l.l_tls_modid), It failed. Obviously, it’s because the info is not
initialized after declaration. Now I have to clean the memory above the stack-
top before I start the loader program to get it works.
