Source: python-cffi
Version: 1.11.5-1
Severity: important
Tags: upstream
Justification: fails to build from source (but built successfully in the past)
User: [email protected]
Usertags: ia64
Builds of python-cffi for ia64 (admittedly not a release architecture)
have been failing lately, per the below excerpts from [1].
Could you please take a look?
Thanks!
