I'm on a risc v board, and gcc seems to crash with `unrecognizable insn` when I try to compile qtgui
Build log: https://gist.github.com/XerneraC/1d5cbb3c9a444e89e4bfcac44508755f

A bit higher up I also noticed a bunch of other things that could be errors, similar to this:

But as the compile went on afterwards, I assume this is not an issue?

The output states this is a reportable bug. We may be able to help you prepare a better bug report, but this will need a bug report. Can you trim down the input to produce a minimal test case for this crash? | Slashhhh wrote: | A bit higher up I also noticed a bunch of other things that could be errors, similar to this: | Code: | Checking for Support for Intel Control-flow Enforcement Technology...

You are using make -j4, so fatal errors may not be immediately fatal. It looks wrong to me that a test for an Intel feature was even attempted on a clearly non-Intel-compatible platform. However, I am not familiar with this package, so it might be able to recover from that. |

| Upgraded from gcc13 to the experimental gcc14 and the issue is gone. |
