Floating Point Error on new rpiOS Bookworm

[kaelaria]

On the new Raspberry PI OS 'Bookworm', on a fresh install, minidsp gives a notice/warning during install and a floating point error when trying to run. Flashing back to 'Bullseye" still works fine.

appears to be an issue with the armhf build installed on either a 32bit OS or a 64bit OS with arm32 added via multiarch, the 64bit build installed on bookwork 64bit is fine

same applies when run on a 32bit OS with a 32 bit cpu (e.g. pi zero), looks like that package is just broken now

@3ll3d00d are you able to dump a stack trace and disassembly of where the invalid FP operation happens?

[3ll3d00d]

I'll try to get something useful

[3ll3d00d]

not sure it helps as the trace seems corrupt and I'm not sure how to dig into that further

#0  0xf7be9a24 in ?? () from /lib/arm-linux-gnueabihf/libc.so.6

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

I decided to try bumping all the versions to current and seeing if I could get it to build given the mention of libc6 and looking at the current rpi build script/docker (which uses a variety of things that seem retired/legacy). This does produce a functioning binary on bookworm, by functioning I mean "doesn't crash immediately" i.e. I haven't tested it beyond that.
