Hey (maybe @sakrejda, @syclik, whoever else might know?),
Ben just upgraded the Jenkins Linux node and now I’m seeing the gamma tests fail with numerical differences that look kind of suspicious to me (like a newer compiler exposing some use of undefined behavior or memory?):
Anyone have ideas?
That does look weird. I just upgraded a box to 18 so I can check.
I think it is the
I don’t recall what the “
9++-7thing” is but I’ll check for solutions on Monday if nobody else gets to it.
Ah yeah, that sounds right. @sakrejda I think it was just that our tests don’t pass under
g++-7 - not sure if anyone found a cause or cure yet.
It looks like they’re up to g++ 7.3. Is that what’s being tested here? We should get Stan math working on recent g++ compilers.
There are unexpected serious numerical differences then NaN differences in:
[ FAILED ] mathMixScalFunGammaP.GoodGammaP (14 ms)
We need to get to the bottom of this. Is there an issue in the math lib for it?
