Hm, dunno what's causing that ...

... but I'm quite sure that patch won't fix it for you, because it was
in code that wouldn't get executed during initdb.

What compiler are you using, for what hardware? Did you use any
nondefault configure or compiler switches? Have you modified the
Postgres sources at all? Which step of initdb gets the failure?
Try running that step under gdb so you can get a stack trace pointing
at the failure location.
