If I change Phobos to be build with -O -release -inline for the release build, it fails to build with this error: std/file.d(2777): Error: function std.file.dirEntries compiler error, parameter 'pattern', bugzilla 2962? dmd: glue.c:758: virtual void FuncDeclaration::toObjFile(int): Assertion `0' failed. make[1]: *** [generated/linux/release/64/libphobos2.a] Aborted make: *** [unittest] Error 2 This may or may not be related to bug# 8250.
Seems to be working fine on HEAD (pre 2.064, Windows x86).
