https://issues.dlang.org/show_bug.cgi?id=19164 Issue ID: 19164 Summary: malloc may be considered pure when failure results in program exit (no need to reset errno) Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: n8sh.secondary hotmail.com A common pattern is to call `core.memory.pureMalloc` and either `assert(false)` or `onOutOfMemoryError()` if allocation fails.
