Bug 10742 – CTFE of std.digest.digest.digest() crashes DMD.

Trying to execute std.digest.digest.digest() in a CTFE context causes DMD (compiled from Git) to crash (at least on win32). import std.digest.md; import std.stdio; template hash(string text) { enum hash = digest!MD5(text); } int main(string[] args) { writeln(hash!"test"); return 0; } Just before crashing, it prints an assertion error message: assert ctfeexpr.c(1816) ae->type->ty == Tsarray || ae->type->ty == Tarray This seems to happen with all available hash types. If the line "copy(range, &hash);" is removed from std.digest.digest.digest(), DMD gives an error message instead of crashing: C:\D\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(1885): Error: Unions with overlapping fields are not yet supported in CTFE C:\D\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d(1862): called from here: nativeToLittleEndianImpl(val) C:\D\dmd2\windows\bin\..\..\src\phobos\std\digest\md.d(443): called from here: nativeToLittleEndian(this._count) test.d(9): called from here: hash.finish() test.d(13): called from here: doHash("test") test.d(17): Error: template instance main.hash!"test" error instantiating However, a little more testing suggests that this error message isn't related to the crash, so it's probably crashing in copy().
