--- Comment #7 from Jeffrey A. Law <law at redhat dot com> ---
It seems like all we've done in the last 10 years is rotate through a set of
bugs in this code.
The whole point of the Richard's original removal of ftruncate was to make
things easier for folks on windows & using simulators (newlib). That patch
introduced a race which led to Jakub's change form Feb 2004 to close the race
condition, but which can leave the file untruncated.
So the question is does this introduce a race similar to what Jakub was trying
to fix back in Feb 2004? What testing has been done to see if there's a race.
Testing similar to Jakub's but scaled up for modern hardware would raise the
confidence level of this patch significantly.

[ Oddly enough, the gcc.gnu.org archives seem to be missing for this thread and
much of Feb2004. ]
