[Python-modules-team] Bug#903263: sip-dev: segfaults building libarcus in Sid

[Petter Reinholdtsen]

Package: sip-dev
Version: 4.19.11+dfsg-1
Severity: serious

Setting severity to serious, as this problem break the build of another
package.

When trying to build a new version of libarcus in Sid from the new git
repository on Salsa, the build fail because sip segfaults.

You should be able to reproduce the problem by running this:

  gbp clone https://salsa.debian.org/3dprinting-team/libarcus.git
  cd libarchus
  gbp buildpackage

Here is some information about the crash.  Not quite sure how to get a
more useful backtrace.
