It's true that pread() is used much less than normal reads, and maybe the cygwin pread() is indeed broken. But it's intriguing how apparently both HP-UX and Cygwin are showing the same breakage. But if git was doing something odd with pread(), then NO_PREAD shouldn't work either, because that just enables the exact same code, except we now supply a pread emulation library function (which does it using "lseek()": not a *good* emulation, but good enough for the very limited use that git puts it to). So yeah, it looks like pread() is broken under cygwin and hpux-11.11. Googling for "pread" "cygwin" does seem to show that it's been buggy at times. Eg: Fixes since 1.5.21-1: ... - Fix pread in case current file offset is non-zero. (Hideki Iwamoto) but I'm a bit surprised that hp-ux has the bug. pread isn't *that* complex.
