[Valgrind-users] how to kill a target program right after memcheck finds an memory error

[sean j. <jin...@gm...>]

Hello,

I want to kill a target binary immediately after memcheck finds an memory
error.

Is there any options to do that?

I checked options list but there seemed no option for that.

As another attempt, I tried to slightly modify source code in memcheck
(mc_errors.c) like this.

#include <stdlib.h>
void MC_(pp_Error) ( Error* err )
{
   const Bool xml  = VG_(clo_xml); /* a shorthand */
   MC_Error* extra = VG_(get_error_extra)(err);

   exit(0);      // this one line is added to kill both valgrind itself and
target as its child
   ...
}

but failed to build with the modification, emitting this error message:

Undefined symbols for architecture x86_64:
  "_exit", referenced from:


waiting for any comments or idea on this issue.

thanks.
