If it's a CTFE variable, it's shouldn't be marked as an extern. t->Tcount++; - if (isDataseg()) + if (isDataseg() && !isCTFE()) { if (isThreadlocal()) { /* Thread local storage */ TYPE *ts = t; ts->Tcount++; // make sure a different t is allocated -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Default arguments are evaluated in the context of the function declaration, not where it's used. So, the temporary generated by the constructor is created in global space! The patch tries to force it back into the function scope, but that doesn't work as you can see if you change foo() to: void foo() { bar(); bar(); } as it fails trying to allocate the same symbol twice. Not sure what the correct solution is at the moment. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=2935 --- Comment #8 from Walter Bright <bugzilla digitalmars.com> 2010-04-27 09:04:17 PDT --- The problem is the code here in expression.c funcParameters(): arg = p->defaultArg; arg = arg->copy(); <-- Danger, Will Robinson! arg = arg->resolveLoc(loc, sc); arguments->push(arg); The arg->copy() is the problem, as it will copy any DeclarationExp's resulting in multiple declarations with the same name. A correct fix will be to do what DeclarationExp::doInline() does, which is for any non-static declarations, create another declaration. A new expression tree walker has to be built to accomplish this. Perhaps a good approach is to create a generic walker that accepts a lambda function to operate on each node. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
