Description Chris Kerr 2023-01-27 06:17:06 UTC

I built sympy and all unkeyworded dependencies with FEATURES=test

Currently there is one failing test, reported upstream as https://github.com/sympy/sympy/issues/24071

The failure exposes a real bug, which on IEEE floats only appears with subnormal numbers but is easier to trigger with PPC64 double-double format. However, even if it is not fixed, the upcoming transition to IEEE long double ABI should fix it.

Reproducible: Always

Comment 2 Chris Kerr 2024-03-28 18:53:25 UTC

After switching to the 23.0 profile (which changes the ABI to ieee-long-double) I tried again - now sympy and all dependencies (including optional dependencies) pass the FEATURES=test tests.
