MicroPython v1.26.0-preview.261.gbcc8d4ee1.dirty on 2025-06-22; linux [GCC 15.1.1] version
Reproduction
- Build mpy-cross with no special flags (
make -C mpy-cross clean && make -C mpy-cross) - Compile
tests/basics/exception_chain.pyinto native code (arch does not matter) withmpy-cross -X emit=native -march=debug tests/basics/exception_chain.py mpy-crosswill crash.
Expected behaviour
Compiling tests/basics/exception_chain.py should not crash mpy-cross.
Observed behaviour
mpy-cross crashes with:
mpy-cross: ../py/emitnative.c:2947: emit_native_raise_varargs: Assertion `n_args == 1' failed.`
Additional Information
If having a multi-arg exception is not supported for native code compilation, then an error message should be printed rather than crashing the compiler.
