The autotester doesn't show any such problems:

https://auto-tester.puremagic.com/

The only failure I see right now is what looks like a random test 
failure on 32-bit linux in druntime.

You list "DMD v2.067-devel-b9dee9e DEBUG." Does that mean that 
you're not using the latest dmd? Make sure that you're using dmd 
master and druntime master when building phobos master. Also make 
sure that all three repos are clean and up-to-date without any 
local changes.

I've tried making a fresh clone of dmd, druntime, phobos on a 
different computer, compiling:

make -f posix.mak MODEL=32

Still the same error. I've no problem compiling stable or 
whatever older version before the above mentioned pull request.
I'm on Debian wheezy for reference.

You might need to put DMD=path/to/dmd in front of make and give 
it the path to the dmd from master so that it uses that rather 
than the one installed on your system.

It picks up dmd from ../dmd/src by default, making it explicit 
makes no difference. I've tried 2.067.1 binary too.

I encountered this when working with CentOS 6 (i.e. somewhat 
outdated). I just commented those asserts out to keep going and 
forgot about it then.

I think I read something (bugzilla issue, source comment, ...) 
that hinted at libc having to do with it, but I can't find it 
now. But CentOS 6's libc is indeed behind that of my usual Ubuntu 
14.10 (2.12 vs 2.19).

Yeah, upgrading Debian from wheezy to jessie solved the issue.

The source is strtold(), part of the C standard library, is returning ERANGE.

Thanks. Should we cater to older compilers and disable those unittests,

Joys of having a compiler that represents all floating point numbers,
and performs all CTFE operations natively.  There is at least some
good news in that others don't follow in DMD's footsteps on this
matter.
