request to allocate 0 bytes as an error, returning NULL. They all return a pointer sized memory chunk (= four bytes) initialized to NULL (= 0) instead. - The alloca() implementation which allocates memory from the system rather than the local stack frame is thread-safe now. It also interacts with the realloc(), calloc(), free() and malloc() functions in that the alloca() cleanup routine is called once alloca() has done its job. If all the memory allocated through alloca() has been released no further calls to the cleanup function will be made. - In the thread-safe library, realloc() permitted two different overlapping calls to succeed in trying to reallocate the same chunk of memory due to a race condition. Fixed. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@15070 87f5fb63-7c3d-0410-a384-fd976d0f7a62
