    • Make recursion_check work for multiple threads · f4c0f888 
      With multiple threads, using an unprotected static variable to check
whether recursion has occured isn't valid, as one thread might have
modified the variable, thus causing another thread to incorrectly
conclude that recursion has occured.  This patch avoids this problem
by using a thread-specific variable for the recursion check.

Regtested on x86_64-pc-linux-gnu.

libgfortran/ChangeLog:

2018-11-23  Janne Blomqvist  <jb@gcc.gnu.org>

	* runtime/error.c (MAGIC): Remove.
	(recursion_key): New variable.
	(recursion_check): Use thread-specific variable for recursion
	check if threads are active.
	(constructor_recursion_check): New function.
	(destructor_recursion_check): New funcion.
