Help I get this ***glib detected*** double free or corruption
Aug 7, 2012 at 7:14am UTC
I'm getting this message when I run my code, but it happens really randomly, i have try with valgrind but it does not happens there for some reason I think that is because it uses single thread and that prevents it, how could I fix it??. Thanks.
the output of valgrind:
