Package: g++-8
Version: 8.2.0-9
Severity: important

Compilation of C++ aplication crash with 'Segmentation fault' when
capturing VLA by reference and also requiring name alias. Code works
on ether g++-7 (Debian 7.3.0-30) and clang++ (6.0.1-9.2). Error is
reproducible even on gcc-snapshot.

crash.cpp
void crash_me(unsigned short sz)
{
  if (sz == 0) return;

  short iov[sz];
  auto fce = [&iv = iov](short value) { iv[0] = 0; };
  fce(1);
}

g++    -c -o crash.o crash.cpp
crash.cpp: In lambda function:
crash.cpp:6:37: internal compiler error: Segmentation fault
   auto fce = [&iv = iov](short value) { iv[0] = 0; };
