http://d.puremagic.com/issues/show_bug.cgi?id=5950 kennytm gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kennytm gmail.com OS/Version|Windows |All 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', ""); } -------------------------- Undefined symbols: "_D6object28__T16AssociativeArrayTaTAyaZ16AssociativeArray3getMFaLAyaZAya", referenced from: __Dmain in x.o ld: symbol(s) not found collect2: ld returned 1 exit status --- errorlevel 1 -------------------------- -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

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 Copyright (C) Digital Mars 1989-2010 All rights reserved. http://www.digitalmars.com/ctg/optlink.html test2.obj(test2) Error 42: Symbol Undefined _D6object28__T16AssociativeArrayTAyaTiZ16Associative Array4keysMFNdZAAya --- errorlevel 1 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
