No, it doesn't. The Coverity Scan builds only run on X86_64 Linux
platforms. When I took over Coverity Scan for CPython many years ago it
was not possible to support multiple platforms and target with the free
edition. I never tried to upload builds from different platforms because
I feared that it might play havoc with the scan history. Should I check
with Coverity again?
Some of these issues have been found by Coverity and I even have patches
for them, e.g. N6 is CID#1299595. I have 13 patches that I haven't
published and merged yet. None of the issues is critical, though. Since
I forgot how to use hg I have been waiting for the github migration.
