Compiler Explorer are still tracking the old "devel/analyzer" branch.
Logged an Issue for them to consider update options:
[BUG]: GCC static analysis branch is outdated/obsolete #4256

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107566
--- Comment #2 from Jamie Bainbridge ---
Thanks for the quick response!
I guess Compiler Explorer doesn't enable static analysis on its "trunk"
compiler, and I also see now its "static analysis" branch is back at gcc-10.
I'll see what I can do

Looks like it also falls over with this testcase:
int main_j;
long x;
int main() {
long crc = x;
for (; main_j; main_j--)
if (crc)
crc = crc >> 1 ^ 20;
}
which fixes the uninitialized use

A slight variation from PR 101221:
template struct S;
template using SS = S;
For comparison, Clang and EDG give exactly the same diagnostic for all examples
above irrespective of C++14/17/20 mode.
