Hi Jerry,
> Thanks for review. Committed to trunk r233436.
The test gfortran.dg/read_bang4.f90 fails on x86_64-apple-darwin15:
a.out(15552,0x7fff7b2e3000) malloc: *** error for object 0x7fb472804c00:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Program received signal SIGABRT: Process abort signal.
If I compile the test with -fsanitize=address, I get
=================================================================
