Hi all, I currenty use valgrind to debug a seg'faulting program but ran into a valgrind message I don't understand: "Bad permissions for mapped region at address" I can't find any information about this message in the manual or the FAQ; a google search didn't help me either.
What does this message mean? Is this an internal error of valgrind? What is going on here?? The complete output of valgrind (valgrind-3.3.0-Debian) is posted after the break.
