[Bug libfortran/22412] New: Fortran B edit descriptor error

["dje at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The negative-z-descriptor.f90 test for PR 22217 fails on the statement 
using '(B65)' format with Fortran runtime error: Error 0.  The error occurs in 
list_read.c:next_char() when salloc_r returns NULL.

Leading up to this point, transfer.c:formatted_transfer() was invoked with 
format B.  As with the previous format statements, the function calls 
unget_format(f), which places the format into the saved_format buffer.

Upon return from the I/O, finalize_transfer() is called leading to 
namelist_read().  The calls to next_char() step through a buffer of spaces 
reaching the end, NULL, causing the error.  The format string in the 
saved_format buffer is never seen.
