Created attachment 1277 repro case The attached repro case causes a ICE. Tested with the latest git head of the dmd 2.064 branch. Omitting -inline will avoid the ICE.

bool b; uint i; ref uint fun() { if(b) return i; else return i; } void analyze() { fun()++; }
Comment #2 by yebblies — 2013-11-14T05:39:48Z
For analyze, the inliner generates (b ? i : i)++; and because the results of the inliner are never run through semantic, it never gets converted to the lvalue version (*(b ? &i : &i))++; This is an inliner bug... The way the inliner interacts with ref is not great.
