+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 (long)thread works too and is portable
+across glibc and musl
+
+Fixes
