Description Xi Jian Zhu 2006-09-21 13:59:54 UTC 
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.

You're doing something outside the spec, there's nothing we can help with.
