Issue ID: 17135 Summary: DMD hangs when compiling in release mode Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: critical Priority: P1 Component: dmd Assignee: nob...@puremagic.com Reporter: cbkbbej...@mailinator.com I'm at a bit of a loss as to narrowing this down, but I've hit a case where compiling a project causes DMD to hang (but only when compiling in release mode). $ git clone https://github.com/Abscissa/SDLang-D.git sdlang $ cd sdlang $ dub test --build=release It will never reach the linking stage, and you can check in your system's process manager that DMD itself is hung with a spiked CPU utilization. If you omit the "--build=release" it will work fine. Maybe someone with better bisect-fu or dustmite-fu than I could get this narrowed down a bit? --
