com32's realloc functionsyslinux-3.20-pre5
Hello list, I've been playing with com32 programs lately and I've come across a a problem with the realloc function in libcom32. The code that rounds up the size looks to be missing a '~' operator, resulting in it truncating every request to a size of 0-15 bytes. The little patch below fixes it up to match the corresponding line in malloc, which makes it work for me. K.
