To detect all errors, runtime checking does not require the program be compiled using the- g option (symbolic). However, symbolic information is sometimes needed to guarantee the correctness of certain errors, mostly rui errors. For this reason certain errors, rui for a.out and rui, aib, and air for shared libraries, are suppressed by default if no symbolic information is available. This behavior can be changed using the -d option of the suppress command and unsuppress command.
The following command causes runtime checking to no longer suppress read from uninitialized memory (rui) in code that does not have symbolic information (compiled without -g):
unsuppress -d rui
