| Subject: | t/convergent0.t fails (with some Math::BigInt versions?) |
On some of my smoker systems the test suite fails:
...
Can't use an undefined value as an ARRAY reference at /usr/perl5.20.1Dp/lib/5.20.1/Math/BigInt/Calc.pm line 476.
# Looks like your test exited with 255 before it could output anything.
t/convergent0.t ..
Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 11/11 subtests
...
Statistical analysis suggests that this happens with some (mostly older) versions of Math::BigInt (theta = 0 means "bad"):
