Squelching glibc memory corruption stack trace output?

Yes: run your code with the environment variable MALLOC_CHECK (the trailing underscore is deliberate) set to 0.

Yes: run your code with the environment variable MALLOC_CHECK_ (the trailing underscore is deliberate) set to 0. This is partially documented in the libc manual, although there seem to be more options than just the 0, 1 or 2 which are suggested there. (The value ends up being passed as the action argument to malloc_printerr() in glibc's malloc/malloc.

C, and the default value seems to be 3. ) The reason you can't redirect it is that it gets written specifically to /dev/tty, unless you have set the environment variable LIBC_FATAL_STDERR_. (I'm not sure this is documented anywhere, but the relevant code can be found here.).

Perfect! Thanks so much. I was looking at __write and that was getting me nowhere.

This worked like a charm. – Buttons Aug 18 at 11:10 @Mike: happy to help! (Please consider marking the answer as accepted.) – Matthew Slattery Aug 18 at 19:47 whoops!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
