The detection is done by parsing\nthe result of `dlerror()` after calling `dlopen()` and looking for\ncertain error strings. On musl libc, the error message is \"Exec format\nerror\", which happens to be `strerror(ENOEXEC)`:\n\n```\n$ cat tmp.c\n#include <dlfcn.h>\n#include <stdio.h>\n\nint main(void) {\n        dlopen(\"libz.so\", RTLD_NOW | RTLD_GLOBAL);\n        puts(dlerror());\n        return 0;\n}\n$ gcc -o tmp tmp.c\n$ ./tmp\nError loading shared library libz.so: Exec format error\n$\n```\n\nThis change fixes the workaround to also work on musl libc.\n\nLink: https://phabricator.haskell.org/D5474","distinct":false,"url":"https://api.github.com/repos/ghc/ghc/commits/64ce6afa21fadd751e1700af145ab77059abadc6"},{"sha":"a5373c1fe172dee31e07bcb7c7f6caff1035e6ba","author":{"name":"Simon Peyton Jones","email":"c710607fca41ac039d19b731ff217fbe4721d9a2@microsoft.com"},"message":"Fix bogus worker for newtypes\n\nThe \"worker\" for a newtype is actually a function\nwith a small (compulsory) unfolding, namely a cast.\n\nBut the construction of this function was plain wrong\nfor newtype /instances/; it cast the arguemnt to the\nfamily type rather than the representation type.\n\nThis never actually bit us because, in the case of a\nfamily instance, we immediately cast the result to\nthe family type.
