Hey, yes the compilation succeeds but running sage fails:

We have the same failure on ppc64el.

Note that this looks like a failure building the docs, however as I explained here:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=849150#10

"Hi, this does not look like a simple out-of-memory, but a bug involving libgomp. A quick Google search of the error message shows that there was some issue involving libgomp, dlopen and GCC years ago, but it's unclear if this is issue here is related.

The error occurs right when the docbuild starts, before it actually attempts to build anything, so my guess is that it would also occur when starting the normal Sage CLI. [..]"

Help with this would greatly be appreciated! I don't think I will have time to look into this myself, and we also need to package 7.5 in the near future.
