I also confirm this on GCC 8.0.1 20180206,
but GCC 7.3 seems okey with code below.

https://godbolt.org/g/kwDaVE

auto lam = [](auto structured_bindable){ // also error with auto&
   auto [first,second] = structured_bindable; // also error with
auto&
   auto test_access = first;
};


g++ (GCC-Explorer-Build) 8.0.1 20180206 (experimental) 
: In lambda function:
:3:35: internal compiler error: in is_normal_capture_proxy, at
cp/lambda.c:288
auto test_access = first;
   ^
mmap: Invalid argument

Minimum example of the bug

Just ran across this as well.  Attached the minimum possible example I could
reduce it to [6 lines, only three of which have semicolons :)].  x86_64 linux
gcc-7.2; 7.3 is affected as well: https://godbolt.org/g/p6LJ5V

Happens on x86_64-linux too, I suspect everywhere.
