When the compiler is instructed to not inline functions with the -fno-inline-functions option, and is also instructed to optimize the program via -O1 or higher, certain circumstances may cause a local copy of the standard library "memset" function to generate erroneous code.

This code contains a call to 'memset' from within memset, meaning that the program will enter an infinite loop.

As a temporary workaround, pass the custom flag '-U_INLINE' to the compiler to avoid the problem.
