Strange compiling error for xTensa

[trinhanhtuan]

Hi,
I meet a strange issue while compiling for ESP32 even with the bare minimal hello-world auto-generated by cargo generate, here is the errors:

   Compiling spin v0.9.8
error: rustc interrupted by SIGSEGV, printing backtrace

What's the output of rustc +esp --version --verbose?

Here we go:

Hi,
I've just compiled an auto-generated hello-world for ESP32-C6, ESP32-S3, ESP32-S2 successfully. Apparently the error is only happened with ESP32 xTensa LX6.

@MabezDev

Not quite sure if this question comes to right place but I still try. Do you know when this bug will be fixed?

Thank you,
Tuan

[MabezDev]

Could you try with the latest 1.82 release? We just updated the LLVM version which might fix this.

Yah, I did it few days ago. It works fine. Sorry not to notify this thread.

[MabezDev]

Glad it's working now!
