[Pkg-emacsen-addons] Bug#863467: verilog-mode: FTBFS randomly on "slow" machines (failing tests)

Sat May 27 10:17:21 UTC 2017

Package: src:verilog-mode
Version: 20161124.fd230e6-2
Severity: important

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
but it failed:

--------------------------------------------------------------------------------

I've put several build logs here:

https://people.debian.org/~sanvila/build-logs/verilog-mode/

The failures happen randomly for me, but only on machines which are
"slow" and have only 1 GB of RAM (plus 1 GB of swap). This is
apparently enough to build the package but the error message suggests
that the failure happens because of an "unexpected speed":

large modules are too slow compared to small modules

If this is the real reason for the failure, packages should not assume
that the CPU performance remains the same during the package build.
The autobuilder could be doing other things other than building packages.

Thanks.
