`ImportError: DLL load failed while importing` when `libgcc 15.1.0` is installed

[jessegrabowski]

Description

An update to the libgcc package is causing windows users to be unable to compile pytensor functions. Issue was reported and debugged by user DrEntropy here.

We should do a release ASAP with a version pin. This is also breaking tests on downstream packages (pymc-extras and pytensor-ml)

[jessegrabowski]

This also made me realize we don't actually test on windows, which seems wrong?

Updated this title to reflect what @maresb reported in #1399

[maresb]

Making some progress towards figuring out what's going on: #general > random cmake test failures all of a sudden

[maresb]

The issue we're hitting: conda-forge/ctng-compilers-feedstock#174

Should be fixed in the latest build by conda-forge/pytensor-suite-feedstock#158

Retroactive fix is incoming

[maresb]

Retroactive fix is awaiting review in conda-forge/conda-forge-repodata-patches-feedstock#1024

[maresb]

This should alternatively be resolved for future versions by #1400.

@DrEntropy, the retroactive fix has been merged, so your original environment specification should now work.
