cross-xtensa-esp32-elf/gcc-10.3.0 works fine.

cross-xtensa-esp32s2-elf/gcc-10.2.0-r5 also fails in the same way, although it succeeded back in January - I'm not sure what's changed.

Is your xtensa-esp32s2-elf-as binary working?

Can you post the following:

1. `xtensa-esp32s2-elf-as --version`
2. `binutils-config -l`

[Comment 3 Michael Moon 2021-04-19 18:51:41 UTC]

Hmm how odd, binutils-config said that xtensa-esp32s2-elf had no version selected at all, how did that happen?

I'll try merging cross-xtensa-esp32s2-elf/gcc again with that fixed

[Comment 4 Michael Moon 2021-04-19 18:55:48 UTC]

That seems to have it fixed - so now I'm just left wondering why it takes a few minutes before failing, and why is the error so obscure compared to the actual root cause?

[Comment 5 Sergei Trofimovich (RETIRED) 2021-04-19 21:22:29 UTC]

I suspec binutils-config (or binutils) has (or had) a bug in handling upgrade. People very rately report similar issues but it's still not clear what sequence of events is needed to lose the registration.

[Comment 6 Michael Moon 2021-04-20 00:52:06 UTC]

I guess we can mark this a duplicate of that bug then - I'll report back if it happens again
