This is the thread I was thinking about: 
https://forum.dlang.org/post/ugxmeiqsbitxxzoyakko@forum.dlang.org

Essentially, copy-pasted code from C results in different behavior in D 
because of the different floating point decisions made by the compilers.

Your quote was: "[The problem is] Code will do one thing in C, and the 
same code will do something unexpectedly different in D."

My response is that it already happens, so it may not be a convincing 
argument. I don't know the requirements or allowances of the C spec. All 
I know is the testable reality of the behavior on the same platform.
