Agree totally. If my interpretation is wrong then I'll happily get on
with my life and let everyone else do the same. I was at that point once
already, but Neil took another close look at the relevant part of the C
standard he dug up and found this potential problem.
I really don't like playing the smart-alec language lawyer here, but I've
been following compiler developments and they are moving in a direction
that makes this relevant. I do want to be sure that we're shipping
correct code, not just code that practically speaking suppresses the
symptoms of its bugs for a while, on most compilers, for the most popular
Moreover, I don't want to go through all of this again when the regression
occurs and we think we've solved it forever and the problem must be
somewhere else. I've been losing enough sleep over what I thought must be
bugs in libpqxx that I just couldn't put my finger on.
