The following script illustrates a problem I am having with gcc1.24
on a Sun 3/60 running SunOS3.5.2.
The crash seems to occur in line 849 of c-typeck.c, in function
build_array_ref. The following subexpression seems to get a
segment violation:
TREE_CODE (TYPE_SIZE (TREE_TYPE (TREE_TYPE (array)))) != INTEGER_CST
