    • Fix fortran common-related error recovery ICE. · 2b3f52a2 
      Upon reverting a symbol in a common block (after throwing an error),
the compiler was ICEing because the symbol's common_block field was set,
but the symbol was not in the common block's list of symbols.

Fixed by both adding the symbol to the common block list and setting
the symbol's common_block field at the same time.
Furthermore, the gfc_add_in_common call is delayed and its result is
ignored, so that its error messages are ignored and the compiler has
the opportunity to give a better error message.
Another gfc_add_in_common call is added later during resolution
to emit again the missing errors.

	PR fortran/67758
gcc/fortran/
	* match.c (gfc_match_common): Delay the common_block pointer
	assignment after error checking.
	Delay the call to gfc_add_in_common attribute after the handling
	of array specs.
	* resolve.c (resolve_common_vars): Call gfc_add_in_common again.
gcc/testsuite/
	* gfortran.dg/common_24.f: New.
