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
