Summary: std.conv.emplace: enforcement is too weak Product: D Version: D2 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nob...@puremagic.com ReportedBy: timon.g...@gmx.ch --- Comment #0 from timon.g...@gmx.ch 2011-09-08 15:35:28 PDT --- T emplace(T, Args...)(void[] chunk, Args args) if (is(T == class)) { enforce(chunk.length >= __traits(classInstanceSize, T), new ConvException("emplace: chunk size too small")); auto a = cast(size_t) chunk.ptr; enforce(a % T.alignof == 0, text(a, " vs. ", T.alignof)); ... } T.alignof is the alignment of the class reference, not the class instance. Classes have to be 16-byte aligned, but the enforcement checks only for 4 byte alignment. This results in segmentation faults in user code, even though the function performs checks. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
