    • 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.

    • PR libstdc++/87308 adjust regex used in std::any pretty printer · 11aa881f 
      The pretty printer for std::any fails when the contained value is a
locally-defined type, because the name in the debuginfo has
cv-qualifiers and ptr-declarators in different positions. The unexpected
format confuses the printer. This makes the printer's regex handle
either format.

This isn't a complete fix because looking up the contained type fails
when there are two types with the same name (defined in different local
scopes). This applies to all closure types defined in a given function,
as they all appear as "func()::lambda" in the debuginfo names.
