I tried to reproduce the bug and failed, so I'm afraid you'll have to step in 
and help debug it. First, please use 26.2 rather than 26.1. Second, please 
simplify the ./configure arguments (there are some duplicates, and 
--enable-libsystemd isn't the right name for the flag). Third, I suggest running 
it under GDB and seeing what exactly goes wrong, e.g., by putting a watchpoint 
on search_regs.start[sub].
