I'm trying to understand why gcc rejects the dynamic array allocation in
the initializer of e (introducing an alias or additional parenthesization
suppress the error). Clang and MSVC happily compile this code. Does gcc
correctly reject this code?

void f() {
typedef void(*arr[T::value]

I'm not a fan of Python and I don't want it added as a dependency to my
favorite compiler. If I would build a minimal system with a toolchain, I
wouldn't want Python to be a mandatory component, so please don't. Thanks.
P.S. I don't mind Perl. It's a legacy tool next to Aw

If Perl is already in the bootstrap set and the awk scripts are hard to
maintain then why can't the awk scripts be rewritten in Pe

yes, after linking phase also I see reference memcpy from PLT.

I need some help for GCC optimization behavior which inserts call to
`memcpy` when
it detects that there is a structure variable assignment.
I have below sample code (copied from a similar gcc-help question):
[ 0] [15:21:40] root@localhost : # cat b.c
struct foo_t {
int x[1048576];
} *fo
