You don't allocate enough space for the return buffer. You need to allocate
2*len + 1bytes to handle the worst cast scenario. The+1is for the null terminating byte.If the count goes above 9, you will output a non-digit character instead of a digit. If the count goes above 256, the digit will wrap around back to
'1'and your compression will have failed to encode the original string.
