Heap corruption detected by tmalloc_large (Galaxy S3 ICS 4.0)

I’m not an expert but my best guess would be that the app using “com.mib_agence.mibclean” is writing into unallocated memory causing damage to the memory allocator and causing it to not work. Is “com.mib_agence.mibclean” your app or a plugin, or another app installed on the phone?
