I could not reproduce the issue in a clean unstable chroot using sbuild
today by building the package three times.

I see similar crashes on sparc and ppc64 [1] thus the problem may not
appear all the time or is in a build-depenency. I'm decreasing severity
for now, but I'm also checking if Valgrind finds something during the build.


Cheers,
Balint
