re PR tree-optimization/91945 (ICE: tree check: expected integer_cst, have var_decl in get_len, at tree.h:5837 since r274997)
PR tree-optimization/91945
* builtins.c (compute_objsize): For ARRAY_REF, only multiply off
by tpsize if it is both non-NULL and INTEGER_CST, otherwise punt.
Formatting fix.
* gfortran.dg/pr91945.f90: New test.
