This maybe a compiler issue.  The package is failing to build because a compile warning is being generated for armv7hl only and the package treats warnings as errors. The following reproduces the warning that doesn't occur for other compiled architectures on fedora:


$ uname -m
armv7l
$ cat repro.cpp
#include <iostream>
#include <stdexcept>

class SomeException : public std::runtime_error {
    public:
        SomeException(std::string m) : std::runtime_error(m) {}
};

int main() {
    try {
        throw SomeException("compiler bug?");
    } catch (const SomeException &e) {
       std::cout << e.what() << std::endl;	
    }
    return 0;
}
$ g++ -Wall repo.cpp -save-temps
repo.cpp: In destructor ‘virtual SomeException::~SomeException()’:
repo.cpp:4:7: warning: pointer used after ‘void operator delete(void*, std::size_t)’ [-Wuse-after-free]
    4 | class SomeException : public std::runtime_error {
      |       ^~~~~~~~~~~~~
repo.cpp:4:7: note: call to ‘void operator delete(void*, std::size_t)’ here

To get the builds working again, I'll likely remove `-Werror` for the package build.

Marek should I create an upstream g++ bug submission for this?

It is most likely https://gcc.gnu.org/PR104213

Thanks Jakub

Yup, just verified my upstream patch fixes this too.  So it's PR104213 for which I'm going to commit a patch now.
