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. - Jonathan M Davis

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. - Jonathan M Davis

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I encountered this when working with CentOS 6 (i.e. somewhat outdated).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, or just leave this be? -- Andrei

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.
