Output:
<source>:1:3: error: ISO C++ forbids declaration of 'a' with no type
[-fpermissive]
a(){[](class{
^
<source>: In function 'int a()':
<source>:1:13: error: types may not be defined in parameter types
a(){[](class{
^
<source>:1:13: error: expected '}' at end of input

Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
Compiler returned: 4
I used C-Reduce on a bigger program to find a smaller test case.
