Unit tests failure on 32-bit architecture

[Harry-Chen]

I'm trying to package highs for debian. The unit tests failed on 32-bit x86 architecture.

Version: 1.9.0
Logs: https://salsa.debian.org/science-team/highs/-/jobs/6894420 (warning: raw logs are very long, DO NOT open with browser)

The following tests FAILED:
	  5 - unit_tests_all (Failed)
	 11 - 80bau3b--presolve=off (Failed)
	 26 - etamacro--presolve=off (Failed)
	 31 - greenbea--presolve=off (Failed)
	 41 - stair--presolve=off (Failed)
	 46 - standata--presolve=off (Failed)
	 56 - standmps--presolve=off (Failed)
	161 - chip-pdlp-no-presolve (Failed)
	162 - e226-pdlp-no-presolve (Failed)
	163 - scrs8-pdlp-no-presolve (Failed)
	166 - stair-pdlp-no-presolve (Failed)
	167 - standata-pdlp-no-presolve (Failed)
	168 - standgub-pdlp-no-presolve (Failed)

Errors are mostly mismatched objective values.
I wonder whether there are some hidden FP precision issues (maybe related to #2000)?

Thank you for raising this. Yes, I think it is related to issue 2000 and the fix is a WIP
