+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);
+|       |                         ^
