https://issues.dlang.org/show_bug.cgi?id=12789 Issue ID: 12789 Summary: Add -transition=nan to emit floating-point variables default-initialized to NaN Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: DMD Assignee: andrej.mitrovich gmail.com Reporter: andrej.mitrovich gmail.com C and C++ do not use NaN, but instead zero-initialize floating-point variables (e.g. in struct fields). When porting or interfacing to such libraries it becomes very easy to forget this and to have odd results at runtime due to D's use of default-initialization to NaN. I propose introducing a -transition=nan flag which will emit the location of all the floating-point variables which are default-initialized to NaN. --
