CVE: NA

-------------------------------------------------

Gcc flag '-fvisibility=hidden' specifies the visibility attribute for external linkage entities in object files.
You can also selectively set visibility attributes for entities by using pairs of the #pragma GCC visibility push
and #pragma GCC visibility pop compiler directives throughout your source program.when we include the hidden.h,
__bss_start and __bss_end went from global symbol to local symbol,so we need to modify the regular expression to
accommodate this change.
