Internal compiler error: access violation. Attempted to read from address 0x0000000000000048 when multiple breaks in a loop

[amaiorano]

Given this HLSL:

void main() {
  while (true) {
    if (false) {
    } else {
      break;
    }
    break;
  }
}

Compiling with latest dxc snapshot:

"C:\dxc\dxc-artifacts (5)\bin\dxc.exe" /T ps_6_5 LoopBreak_FromLoopBodyDirect.hlsl
Internal compiler error: access violation. Attempted to read from address 0x0000000000000048

If we remove either one of the two breaks, it compiles. If we change the if (false) to if (true) it also compiles.
