glibc detected output descriptor

[matias]

Hi everyone. I'm working on a fuzz-testing application right now. I'm trying to figure out on which descriptor does the "glibc detected....." get written to: Since my application is testing others, this is quite a common message therefore i don't want the user to be spammed with this message every time it occurs(it would be occuring on the fuzzer's target application, not in mine).

I'm doing a fork, closing stdout and stderr so far. However, this message still appears. Does anybody know how can i supress it?

Thanks in advance!
