Bug 17831 – [ICE] Internal error: backend/symbol.c 1039: foreach inside a switch statement

Taken from recently introduce test case. https://github.com/dlang/dmd/pull/7120 --- int bug17807(){ int y=0; Lswitch: switch(2){ { case 0: break; } enum x=0; struct S{ enum x=0; } int foo(){ return 0; } default: y=x+S.x+foo(); foreach(i;1..5) case i: break Lswitch; } return y; } --- Removing the 'static' in foreach results in a compiler ICE.

Reduced test: --- void main() { switch (2) { foreach (i; 0 .. 5) case i: break; default: break; } } ---

Ah, don't even need a foreach. --- void main() { switch (0) { int i = 0; case i: break; default: break; } } ---
