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.

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_READ_LINE: foreach (char [] line; stream) {[...]continue _READ_LINE;[...] specs: | If continue is followed by Identifier, the Identifier must be | the label of an enclosing while, for, or do loop, and the next | iteration of that loop is executed.
