-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Bruno Haible on 3/30/2008 2:44 PM: | Hi Eric, | |> Of all the |> systems I tried, I did not find a single one that was fully C99 compliant. | | I'd like to document the flaws across more platforms. Do you have a set of | test programs, one snippet for each bug you found so far, that I could run | on a variety of systems? I could try to extract them from the unit test that | you committed, but you probably already went through this process, I assume?
test-strtod.c is all I had; but I intentionally made it catch all errors rather than aborting on the first; then correlated the line number failures to the platform bugs. The only machines I had access to were glibc 2.3.4, cygwin 1.5.25-7 through -11 (-11 contains several of my patches for bugs caught in -7), mingw, OpenBSD 4.0, and Solaris 8. And there are probably still bugs out there that my unit test did not catch - for example, several years ago, I found that I could put Sun's javac compiler in an infinite loop when parsing a thousand-character decimal that was just barely less than the smallest normalized number minus .5 ULP; and I have suspicions that the decimal-to-float algorithm in Sun's compiler is shared among many other platforms (many such algorithms are based on David M. Gay's open source implementation). test-strtod.c is big, but it could certainly be made bigger as we find more bugs (and more importantly, as gnulib's replacement is beefed up to be more accurate). - -- Don't work too hard, make some time for fun as well!
