@kxxt Just to check - this is an issue at runtime when you run with --riscv-c-extension? I was a bit confused by this issue saying it was a compilation failure and thought it was something that showed up when you were running the node build ...

Scratch that - have confirmed the problem with a v25.x-staging build and also that this fixes it. Failure was as follows:

sxa@bananapif3:~$ ./node25xs1-vanilla --riscv-c-extension
