From 90fdb0ae0418f7907f09b763343a457bdf6855fa Mon Sep 17 00:00:00 2001

Subject: [PATCH] tests: Make pthread_detatch call portable across platforms
pthread_t is opaque type therefore we can not apply simple arithmetic to variables of pthread_t type
this test needs to pass a invalid pthread_t handle, typcasting to uintptr_t works too and is portable
across glibc and musl
Fixes
| pth_detached3.c:24:25: error: invalid use of undefined type 'struct __pthread'
| 24 | pthread_detach(thread + 8);
| | ^
