Ahh, ok. Should I mark any buzilla bugs that I get as duplicates of that one?

It's this bug:
Unexpected [-Werror=use-after-free] warning only on arm7hl build of code
It's fixed in gcc-12.0.1-0.4.fc36. Under local mock, you'll have to use
--enablerepo=local because there hasn't been a compose in a while
(apparently).

Rawhide arm compiler bug?
Forgive me if I'm pointing out a known issue, but I haven't noticed anything on
the list about this yet...
I keep getting sent rawhide build errors for my project. They only appear to
occur on the avmv7hl platform. It builds fine on all other architectures.
The errors are like:
sha1.cpp: In member function 'sha1::~sha1()':
sha1.cpp:34:1: error: pointer used after 'operator delete(void*, unsigned int)'
[-Werror=use-after-free]
34 | }
| ^
The code for ~sha1() is:
sha1::~sha1() {
delete pvt;
}
Line 34 is that closing bracket.
The code definitely isn't using the pointer after it's been deleted. Could
this be a compiler bug?
Thanks,
David
