examples/micropython: floating point exception while testing on native #15870

leandrolanzieri · 2021-01-27T15:38:01Z

Description

While running the test for the examples/micropython application on native, a floating point exception is raised. I tried building in Docker and I get the same issue. Current master pointing to 4509dc6.

Steps to reproduce the issue

Build examples/micropython for native
Run make test

Expected results

Passing test

Actual results

Floating point exception is raised

when I ran this test without the python script it seems to pass :/

There might be a race condition.

What I've noticed is that the timer seems to be fired way before than expected:

>>> t.set(500000)
t.set(500000)
>>> while a==0: pass
while a==0: pass
... 

/* It gets here almost immediately... */

>>> utime.time()
utime.time()

Hmm got another one. While running tests/thread_float:

RIOT native interrupts/signals initialized.
LED_RED_OFF
LED_GREEN_ON
RIOT native board initialized.
RIOT native hardware initialization complete.

Could this be related to #495?

Sorry 😅. But now at least, there is a cross reference here as well 😁
