jit compilation no longer works on google colab after v0.51.1

[thomasdkelly]

Hi I have a module that relies on numba jit compiled functions which i run on google colab. However, after version 0.51.1 the functions no longer compile on colab but do locally. When i exit the compilation, the line of code it is stuck on is in the controlflow file. I assume it is because of the changes made in "PR #6146: Fix compilation slowdown due to controlflow analysis" though i do not know why exactly.

Is there any reason why these changes mean the jit compilation no longer works in colab?

Thanks
Tom

Thanks for the report. I would guess from the description you are hitting this bug: #6186 that was introduced in 0.51.1, good news is it's fixed in #6195 and 0.51.2 with this fix in is shipping as I type this.
