This is related to Bug 4724, but I'm filing it as a separate issue and labeling
it a regression because something (probably the more aggressive inlining that
was added for 2.058) expands the effects of that bug in ways that break
previously working code. If we can't fix the compiler bug then we need to work
around it to avoid an awful regression.
import std.string;
void main() {
"".indexOf("");
}
dmd -O -inline -release -c test.d
/home/dsimcha/dmd2/linux/bin64/../../src/phobos/std/algorithm.d(2970): Error:
function
std.string.indexOf!(char,char).indexOf.simpleMindedFind!(__lambda6,const(char)[],const(char)[]).simpleMindedFind
is a nested function and cannot be accessed from main
Here's a reduced version that doesn't import any Phobos modules:
void main() {
"".indexOf("") ;
}
void indexOf(const(char)[] s, const(char)[] sub) {
find!((dchar a, dchar b){return a == b;})
(s, sub);
}
void find(alias pred)(const(char)[] haystack, const(char)[] needle) {
pred(haystack[0], needle[0]);
}
$ dmd -c -O -inline -release test.d
test.d(11): Error: function test.indexOf.find!(delegate pure nothrow @safe
bool(dchar a, dchar b)
{
return cast(uint)a == cast(uint)b;
}
).find is a nested function and cannot be accessed from main
