http://f17.aaa.livedoor.jp/~labamba/?BugTrack%2F20 This bug reported by nagadomi in japanese d language wiki. I don't know, this bug already reported. But, I write this. if (alreadyReported) writefln("sorry. m(_ _)m"); In foreach of the class with the onApply method, When continue with the label was used, it was displayed, "Internal error: s2ir.c481". I used compiler DMD v0.129. I can't download DMD v0.130. import std.stream; void parse(Stream stream) { _READ_LINE: foreach (char [] line; stream) { if (line.length == 0) { continue _READ_LINE; } } } int main() { return 0; } thanks, Hiroshi Sakurai.

Oh. Continue statements in foreach is not in the spec. umumumumumu... Please write that Continue Statement in foreach can be used for the specification. I think "this is natural". -sakurai

However, the fact that it crashed the compiler with an "internal error" still makes it a noteworthy bug.

It is an error to use a non-existent label following continue, and it is reported by the compiler, but that really is off-topic. As to the original post, it is a compiler bug. If you 'typedef char[][] Stream' then the code compiles fine. It appears that UDT's having an opApply will crash the compiler just as the OP said. - Dave
