http://d.puremagic.com/issues/show_bug.cgi?id=2469 Summary: arbitrary struct accepted as struct initializer Product: D Version: 1.035 Platform: PC OS/Version: Linux Status: NEW Keywords: accepts-invalid Severity: normal Priority: P2 Component: DMD AssignedTo: bugzilla digitalmars.com ReportedBy: kamm-removethis incasoftware.de The following code compiles struct Foo { double d; } struct Bar { byte b; } void main() { Foo foo; Bar bar = foo; } even though Foo is not implicitly convertible to Bar. In contrast, assigning Foo foo; Bar bar; bar = foo; fails as expected. --

The following, for instance, causes it: struct Small { uint x; } struct Large { uint x, y, z; } Small foo() { return Small(); } void main() { Large l = foo(); } // bang! -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=2469 There are two completely different bugs in this report. One is the implicit conversion one, which is a bad code generation bug. The ICE is actually a quite different bug. Here's a test case which doesn't involve the initialisation bug. struct Small { uint x; } struct Large { uint x, y, z; } Small foo() { return Small(); } void main() { Large l; Small s; l = cast(Large)foo(); } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=2469 There's a patch for the original bug in bug 2702. It's unrelated to the ICE. (It's really annoying when new bugs are reported in the comments for existing bugs, it's not clear what to do with them). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
