Zero-length allocation with posix_memalign()

I recently submitted a patch to the vlc developers that prevents a crash on FreeBSD 8.0 by not calling posix_memalign() with a size argument of zero. A simplified test case would be: #include int main(int argc, char **argv) { void *ptr; posix_memalign(&ptr, 16, 0); return

thanks. i remembered fprintf being buffered, but i always thought \r would also empty the buffer. now that explains everything. ;-) alex Jilles Tjoelker schrieb am 2009-07-05: > On Sun, Jul 05, 2009 at 01:42:01PM +0200, Alexander Best wrote: > > i'm running something similar to this pseudo-code i
