glibc destroys[1] the passed pthread_attr_t if pthread_getattr_np() fails. Destroying it again leads to a segfault. Fix it by only destroying it on success for glibc. [1]: https://sourceware.org/git/?p=glibc.git;a=blob;f=nptl/pthread_getattr_np.c;h=ce437205e41dc05653e435f6188768cccdd91c99;hb=HEAD#l205
…ibcs The calling convention of pthread_getattr_np() is to initialize the pthread_attr_t, so _destroy() is only necessary on success (and _init() isn't necessary beforehand). On the other hand, FreeBSD wants the attr_t to be initialized before pthread_attr_get_np(), and therefore it should always be destroyed afterwards.
This made too many assumptions about platforms, breaking some things. Will need to be added later with a better way of gating on proper alignment, without hardcoding cfg(target_arch)s.
test is already in scope, no need to use the full path
