In linux man memcpy:
	void *memcpy(void *dest, const void *src, size_t n);

DESCRIPTION
       The  memcpy() function copies n bytes from memory area src
       to memory area dest.  The memory areas  may  not  overlap.
       Use memmove(3) if the memory areas do overlap.

On solaris 2.6 man memcpy:
	void *memcpy(void *s1, const void *s2, size_t n);

     memcpy() copies n bytes from  memory  area  s2  to  s1.   It
     returns s1.


You seem to copy from the outBuff into the buffer_ptr, which is
const in the first example.

Try to swap the buffer_ptr and outBuff arguments.
