Bug 14853 – [REG2.066] DMD segfaults with the cast from mutable struct new to shared

From: http://forum.dlang.org/thread/[email protected] Tweaked test case: struct sQueue(T) { struct sNode { T mfPayload = T.init; union { typeof(this)* mfPrev; shared(typeof(this)*) mfShPrev; } union { typeof(this)* mfNext; shared(typeof(this)*) mfShNext; } } sNode mfRoot; void pfPut(T v, sNode* r = null) { shared n = new sNode(v); // problem! } } void main() { auto b1 = new sQueue!uint; }

I confirmed that this is a regression from 2.066.
