What steps will reproduce the problem?
nick@fusrodah:/tmp$ cat openal-asan-trigger.cpp
#include <AL/al.h>
#include <AL/alc.h>

int main(){
ALCdevice* d = alcOpenDevice(0);
alcCloseDevice(d);
}
nick@fusrodah:/tmp$ clang++ -fsanitize=address openal-asan-trigger.cpp -lopenal
nick@fusrodah:/tmp$ ./a.out
=================================================================

AddressSanitizer can not describe address in more detail (wild memory access suspected).

What is the expected output? What do you see instead?
No error from ASAN, the thing is properly allocated.

What version of the product are you using? On what operating system?
Asan from clang-3.4 on Arch linux.

Please provide any additional information below.

OpenAL bug report (with the conclusion that it doesn't error when malloc is used instead
of alligned_alloc): https://github.com/kcat/openal-soft/issues/1
