[Octave-bug-tracker] [bug #48365] __run-test_suite_ FAIL for assert.m (tolerances)

[Markus Mützel]

Follow-up Comment #18, bug #48365 (project octave):

This might be related to a known bug in mingw-w64 [1]: The mantissa is off by
1 bit when calling std::pow with a variable. Results with literals are
correct.
I checked with mingw-w64 5.0.2 and gcc 7.1 (patch #9269) and the bug is still
present.
A proposed workaround is to use std::powl which is not affected.

For the time being it might be easier to increase the tolerance for the
affected tests (this and bug #48364) or to mark them as xtest.
