OpenBSD: Improved Memory Allocation, Beta Testing 3.8

"Theo points out that these changes have a couple of significant impacts. He explains that for over a decade efforts have been made to find and fix buffer overflows, and more recently bugs have been found in which software is reading before the start of a buffer, or beyond the end of the buffer. With these recent memory allocation changes, such an attempt will cause the application to coredump with a SIGSEGV signal."
