Broken bison release (or gcc-overoptimization), you need to upgrade to
the fixed version (1.875a?) or edit the template code in
/usr/share/bison/yacc.c.

The fix is something trivial like adding a semicolon right after the
yyerrlab1: label so that the compiler doesn't optimize it away.

That probably works as well, but resolver_parser.c is generated from
resolver_parser.y and the bison template code (where the actual problem
is). So this patch would have to be reapplied whenever bison rebuilds
the .c file.

This depends on whether you have the openssl development headers
installed. If openssl-dev exists it should try to use their
implementation, otherwise it should use the 'reference C implementation'
which is built and included in lib-src/base/libbase.a.
