I use QEMU to test klibc changes on as many architectures as possible.
For a long time I used QEMU 3.1 with some cherry-picked bug fixes.
All the GNU-built binaries would run successfully on that, but Clang-
built binaries for some architectures did not.
Switching klibc to the time64 kernel API forced me to update to QEMU
7.2. This introduced regressions for shared-library executables for
armhf and riscv64.
that's definitely not good. The problem here seems to be that apparently
no one knows about these problems, so no one can fix them either.
For the very least, - since I know very little about actual emulation
internals myself, - maybe there's a way to bisect things? Some simple
reproducer for the segfault, which don't use 64bit time_t so can run
on qemu 3.1 and 7.2?
Ben, I'd really love to have the bugs fixed. But I need some of your
knowledge for that too ;)
Thanks!
