The below ends with SEGV. ---------------------------- import std.stdio; void logout( lazy const(char)[] msg ) { writeln( msg ); } void main() { string str = "hello world"; logout( (){return str;}() ); // closure 1 try throw new Exception( "exception!!" ); catch( Exception e ) { logout( e.toString ); // closure2 SEGV : e is null. } } ---------------------------- Build : dmd 2.052 on Windows Vista WOW64. Without `closure 1', the code executed successfully.

The "x86_64" platform means the executable is 64-bit. Only Linux has 64-bit output. BTW, reproducible on Mac OS X also.

Heh, on git HEAD (b9b5c063d7f44b879d6fde74f400ff094ba85707), this code causes an ICE: dmd: struct.c:251: static void AggregateDeclaration::alignmember(structalign_t, unsigned int, unsigned int*): Assertion `alignment > 0 && !(alignment & (alignment - 1))' failed. Aborted

P.S. This is on Linux 64-bit.
