It is based on Googled: http://www.cs.rpi.edu/~szymansk/OOF90/bugs.html#5 When a pointer is declared its status is undefined, and cannot be safely queried with the associated intrinsic. -> nullify(VARNAME) + https://software.intel.com/en-us/forums/intel-fortran-compiler-for-linux-and-mac-os-x/topic/268786 ALLOCATE is not supposed to initialize the array. -> Remove checks like an initial print is: \\( *0, *0, *0...\\) These regressions remain: -PASS: gdb.fortran/library-module.exp: print var_i in lib +FAIL: gdb.fortran/library-module.exp: print var_i in lib -PASS: gdb.fortran/library-module.exp: print var_i in main +FAIL: gdb.fortran/library-module.exp: print var_i in main I believe it is more a GDB bug (in a code contributed by me), filed: gdb.fortran/library-module.exp false regression on GCC upgrade https://sourceware.org/bugzilla/show_bug.cgi?id=19635 gdb/testsuite/ChangeLog 2016-02-14 Jan Kratochvil <jan.kratochvil@redhat.com> Fix compatibility with recent gfortran-5.3.1. * gdb.fortran/vla-history.exp (print vla1 allocated) (print vla2 allocated, print $2, print $3): Remove (print $4): Rename to ...
