Compilation of v1.27.0 fails on s390x and loongarch64

openby maribuopened 2025-12-13updated 2026-03-16
bugport-unix

Port, board and/or hardware

unix port (Alpine Linux)

MicroPython version

MicroPython Version 1.27.0 on Alpine Linux Edge (GCC 15.2.0)

Reproduction

Build the UNIX port on Alpin Linux Edge on an s390x or an loongarch64 machine. One could use the package build recipe in https://gitlab.alpinelinux.org/alpine/aports/-/tree/master/community/micropython and then use build -r to reproduce it.

Expected behaviour

MicroPython builds without errors.

Observed behaviour

Building on Alpine Linux for s390x and loongarch64 with:

main.c: In function 'parse_integer.constprop':
main.c:237:9: error: variable 'base' might be clobbered by 'longjmp' or 'vfork' [-Werror=clobbered]
  237 |     int base = 10;
      |         ^~~~
main.c:248:10: error: variable 'valid' might be clobbered by 'longjmp' or 'vfork' [-Werror=clobbered]
  248 |     bool valid = false;
      |          ^~~~~
cc1: all warnings being treated as errors

Additional Information

Without access to real hardware, ways to reproduce are:

  1. The alpine linux docker + QEMU
  2. The Alpine CI (runs upon opening a Merge Request)

mboot fails to build

Port, board and/or hardware

ARDUINO_PORTENTA_H7

MicroPython version

git describe --dirty: v1.24.0-181-g495ce91ca; Building for ARDUINO_PORTENTA_H7.

But the board says MicroPython v1.25.0-preview.180.g495ce91ca on 2025-01-07; Arduino Portenta H7 with STM32H747 when I flash mpython (it already has mboot I guess).

I've also tried this for tag v1.24.0 and the same error occurs.

Reproduction

Following build instructions from here: https://github.com/micropython/micropython/tree/master/ports/stm32#build-instructions

git clone https://github.com/micropython/micropython.git
cd micropython/
make -C mpy-cross
cd ports/stm32/
make BOARD=ARDUINO_PORTENTA_H7 submodules
make BOARD=ARDUINO_PORTENTA_H7
make -C mboot BOARD=ARDUINO_PORTENTA_H7

Expected behaviour

mboot builds

Observed behaviour
