[Debian-med-packaging] Bug#949204: macs FTBFS on most architectures. test failures

[peter green]

Package: macs
Version: 2.2.6-3
Severity: serious

The new upload of macs to unstable failed to build on most release architectures (curiously it built successfully on most debian-ports.org architectures, though it's possible that some of them are building with nocheck), it failed in several different ways.

On arm64 and ppc64el the testsuite seems to fail due to floating point rounding discrepancies e.g.

> 14.9.6 checking callpeak_pe_broad run_callpeak_bedpe_broad_peaks.broadPeak ...
>   ... failed! Difference:
> 4c4
> < chr22	17398268	17398740	run_callpeak_bedpe_broad_peak_4	279	.	13.95538	30.73891	27.95395

i386, mips64el and mipsel, failed with a NaN verses 0 discrepancy

> E       0.0
> E
> E       - (-48.6784, nan)
> E       ?            ^^^
> E
> E       + (-48.6784, 0.0)
> E       ?            ^^^
and s390x failed with a zerodivisionerror

>    File "MACS2/IO/Parser.pyx", line 1153, in MACS2.IO.Parser.BAMPEParser.build_petrack
> ZeroDivisionError: float division
>   ... error/warning found!
