This seems to happen when there is an identical associative array declared in
an imported file, but that is not used to generate code from. Obviously dmd
believes it does not need to generate the template code again. Here's a reduced
test case:
-
module test1;
int[string] map;
-
module test2;
import test1;
int main()
{
int[string] m;
return m.keys.length;
}
-
compiling this with dmd test2.d with the latest compiler from github yields
OPTLINK (R) for Win32 Release 8.00.11

Reproducible on Mac OS X. The missing symbol demangled is
immutable(char)[] object.AssociativeArray!(char,
immutable(char)[]).AssociativeArray.get(char, lazy immutable(char)[])
It is probably a regression since I can't reproduce it on ideone which uses
2.042, but it may simply be that the error doesn't manifest on Linux.
Reduced test case:
--
import std.stdio; // -- the import is necessary to trigger the bug!
void main() {
string[char] tab; // -- must be a string[char]?
tab.get('c', );
}
