-O2 is enabled, which I guess renders the issue invalid? If not, anyone from Espressif is free to reopen it.

[KaeLL]

Never mind, I'm getting the same thing even with -Og

[igrr]

@KaeLL would it be possible for you to attach the core dump binary and the corresponding ELF file?

[KaeLL]

Yes, but not publicly. Suggestions?
