Hello,
There is a simple bug in method "Post_dominate" in file be/com/cfg_bash.h.
A boolean return value is missed after the do-while loop. Compiler may
generate unexpected code(whenever invoking Post_dominate method, it is
always return true if using opt-version compiler).
The patch is as follows:
