[Debian-med-packaging] Bug#828359: Bug#828359: iva: FTBFS with openssl 1.1.0

[Sascha Steinbiss]

Hi Kurt,

thanks for the rebuild and for reporting this FTBFS.

I was curious indeed when I saw iva fail, given that it does not use OpenSSL at all.
Investigation of the build log led me to believe that the cause of this is a problem with Python’s multiprocessing module in pbuilder runs, which I suspect is connected to /dev/shm not being writable. This is a problem that also occurs in the rebuilds done by the Reproducible Builds folks [1].

I am not sure if I can just close this bug as it does not relate to OpenSSL and I should probably file a bug indicating this pbuilder associated issue.

Thanks and best regards,
Sascha
