Bug#914470: gdc-8: ICE in gdc on call to defaulted alias template parameter that is a delegate literal

Package: gdc-8
Version: 8.2.0-9
Severity: normal

# cat perf_min.d

module perf_min;
void run(alias prep = delegate() {})() {
void main() {

$ gdc perf_min.d
perf_min.d: In function ‘run’:
perf_min.d:3:5: internal compiler error: in get_frame_for_symbol, at d/d-codegen.cc:2161
0x7f626f339b16 __libc_start_main

gcc version 8.2.0 (Debian 8.2.0-9) 

For comparison, when compiling using ldc2:

LDC - the LLVM D compiler (1.12.0):
  based on DMD v2.082.1 and LLVM 6.0.1
  built with LDC - the LLVM D compiler (1.12.0)
  Default target: x86_64-pc-linux-gnu

there are no issues, and generate code looks correct.
