--- Comment #4 from Tobias Brunner <tobias at strongswan dot org> ---
Note that changing the macro so that instead of

  static typeof(_cb_parse)* parse = _cb_parse;

it declares the function like this

  static _Bool (*parse)(void*, char* in) = _cb_parse;

seems to fix the issue (see my update here:
https://github.com/strongswan/strongswan/issues/1053#issuecomment-1131356912).
