This calls

pthread_key_create (ATCB_Key'Access, null);

at s-tpopsp-posix-foreign.adb:50; here ATCB_Key is an aliased global
variable declared at s-taprop-posix.adb:86, so its access value cannot
be null.  MAybe what is happening is that pthread_key_create is itself
an unresolved symbol?  What does

ldd music123


What does

ldd /usr/lib/i386-gnu/libgnarl-4.6.so.1


They should be both linked with libpthread, or Hurd's equivalent.
