__stack_chk_fail routine is runtime part of stack protector compiler

feature. It's implemented in libc and represents die routine when stack

corruption is detected.

Calls are generated by compiler and injected into user functions when

-fstack-protector* options are used.

__stack_chk_fail_local is wrapper for __stack_chk_fail. Compiler generates

wrapper calls instead for PIC code only and only on IA32 for optimization
|

purpose (see gcc/config/i386/i386.c). Wrapper body is always included into
|

executable or library. This is the idea of optimization.
|
||||
|
||||
Glibc is doing this via libc_nonshared.a which is linked automatically
|
||||
everytime with libc.so. In bionic we have to bring it within crtfiles
|
||||
because libc.so is real library and not a link script like libc.so at glibc.
