Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gitlab.archlinux.org/archlinux/packaging/packages/gcc/-/issues>
for instructions.
Source file:
#include <QCoreApplication>
import photoDeltaFetchingBenchmarks;
int main(int argc, char** argv)
{
QCoreApplication app(argc, argv);
BM_get_photo_delta();
BM_fetch_photo_delta();
}
I have generated a preprocesed source file with -freport-bug but it is too big
to include.
Problem occurs on
$ gcc --version
gcc (GCC) 14.1.1 20240507
Arch Linux
