Hi Mo,
Thanks for your forebearance with this string of Ubuntu bug reports. I'm
hopeful that once we manage to resolve this one, the double-conversion
package will be in sync again between Debian and Ubuntu :)
The latest upload of double-conversion is failing to build from source on
ppc64el in Ubuntu, because Ubuntu builds ppc64el with -O3 by default instead
of -O2, and this additional optimization level somehow causes a public
constructor to be lost from the exported symbols:

This problem is also reproducible on amd64 if I raise the optimization level.
This may well be a problem with the toolchain, but for the moment I've
worked around this by forcing the optimization level down to -O2 as in the
attached patch.
Thanks for considering,
