4.4.6, 4.5.3, and 4.6.2 (r179116) gives

pr54940.f90:4.30:

    integer :: j(:), bug(size(j-1))
                              1
Error: Variable 'j' cannot appear in the expression at (1)
pr54940.f90:4.19:

    integer :: j(:), bug(size(j-1))
                   1
Error: Array 'j' at (1) cannot have a deferred shape

The ICE starts with 4.6.3. The ICE occurs at

  gcc_assert (result->symtree
              && (result->symtree->n.sym->attr.flavor == FL_PROCEDURE
                  || result->symtree->n.sym->attr.flavor == FL_UNKNOWN));

introduced by r183314 and the backtrace is

... which was Tobias' fix for PR 51904. I think the most straightforward thing
would be to just remove the assert again:


Index: gcc/fortran/expr.c
===================================================================
--- gcc/fortran/expr.c    (revision 192392)
+++ gcc/fortran/expr.c    (working copy)
@@ -4606,9 +4606,6 @@ gfc_build_intrinsic_call (const char* name, locus
   result->value.function.isym = isym;

   result->symtree = gfc_find_symtree (gfc_current_ns->sym_root, name);
-  gcc_assert (result->symtree
-          && (result->symtree->n.sym->attr.flavor == FL_PROCEDURE
-          || result->symtree->n.sym->attr.flavor == FL_UNKNOWN));

   va_start (ap, numarg);
   atail = NULL;


In a valid-code context the assert surely makes sense, but here it seems to
choke on the fallout of the two errors.

--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> 2013-01-07 15:23:51 UTC ---
I believe this bug is fixed by the just committed patch for PR 55852, which
restores the error message of comment 1. The commit is:

Date: Mon Jan  7 11:10:53 2013
New Revision: 194966
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=194966

Thus, I mark this PR as duplicate.



Thanks for the report and sorry for the breakage.

*** This bug has been marked as a duplicate of bug 55852 ***
