Created attachment 52208

gcc12-pr104031.patch
This seems to work for the testcase, but dunno if there aren't better fixes.

That last testcase isn't very good for the testsuite, because 0 is pretty
common value on the stack, so even without the store the chances that it will
be already zero are high.
42 is less likely...

gcc-11 for comparison did not seem to have `struct InfoD.2399 D.2453 =
{.arityD.2402=0};` style nodes and encoded stores explicitly:
main.cc.244t.optimized:
voidD.48 _GLOBAL__sub_I_main ()
{

Great test, Andrew!
Something is completely dropped initialization of Info{} input argument to
s_op. As if it's lifetime ends before RegisterPrimOp{} enters:

Reduced testcase without any headers:
struct vector
{
vector(){} ~vector(){}
};
struct Info {
vector args;
int arity = 0;
};
struct RegisterPrimOp
{
[[gnu::noipa, gnu::noinline]]

I can remove std::string but not figure out how to remove std::vector yet:
#include
#include
struct string
{
string(int){}
};
struct allocator
{
allocator(){}
};
struct vector
{
