Joseph,
here is the patch for c_expr_sizeof_type you had suggested.
Best,
Martin
Evaluate type arguments of sizeof that are structs of variable size [PR101838]
Evaluate type arguments of sizeof for all types of variable size
and not just for VLAs. This fixes PR101838 and some issues

Here is a patch which changes the behavior of sizeof
when applied to structs of variable size (a GNU
extension) to evaluate its arguments as it does
for VLAs. This is a breaking change, but it seems
this is required if we want to fix [PR29970] (and
it is also more consistent). Together with the
