Hi, Eli! This was 24.5 - but not just 10 minutes ago I posted that pre-release 25.1-rc1 built correctly. So this bug can most certainly be marked as resolved I guess :)

Using the new glibc, v2.24, and GCC 6.1

Any attempt to run 'temacs' fails with a segment fault. It appears that
the call to 'malloc' inside the 'calloc' function in Emacs' gmalloc.c
file starts to recurse, and eventually hits a segment fault after
recursing 10,000+ times. Here is the stack trace at the beginning of
this nested recursion hell.

I don't know why the call to malloc is turning into a call for the
calloc in gmalloc.c, but I think whatever is doing that is causing this
problem.

Any thoughts? Anything else needed?

You don't say what version of Emacs you tried to build.  I think this
is already fixed in the development sources.
