--- Comment #6 from Don clugd...@yahoo.com.au 2010-01-26 00:06:30 PST ---
Cause: If global.errors !global.gag, TemplateInstance::semantic doesn't set
'inst'. So this is a possible patch (not recommended) inside template.c:
{
if (!global.gag)
{
/* Trying to soldier on rarely generates useful messages
* at this point.
*/
fatal();
}
+inst = this; // error recovery
return;
}
===
But, on the other hand, most other functions in expression.c only run
ti-semantic() if there are global.errors.
So this patch to expression.c line 6252 may be better:
Expression *DotTemplateInstanceExp::semantic(Scope *sc)
{
#if LOGSEMANTIC
printf(DotTemplateInstanceExp::semantic('%s')\n, toChars());
#endif
Expression *eleft;
Expression *e = new DotIdExp(loc, e1, ti-name);
L1:
e = e-semantic(sc);
if (e-op == TOKdottd)
{
+if (global.errors) return new ErrorExp();
DotTemplateExp *dte = (DotTemplateExp *)e;
TemplateDeclaration *td = dte-td;
The same problem occurs in mtype.c, line 6613, 7101, inside ::dotExp(), for
structs and classes, and they should probably have the same fix.
(they shouldn't be running ti-semantic() if there are global errors).
