very closely related is this problem, which can probably be fixed at the same time:

$ cat b.f
       character*8 A
       data A /'12345678'/
       character*4 B
       read(A,'(A)')B
       print*,B
       end
$ /usr/local/bin/current/bin/gfortran -static b.f
$ ./a.out
Segmentation fault (core dumped)
$ g77 b.f
$ ./a.out
 1234
