Comment (by sebastic):

 The GCC 6 isnan issue is causing a Release Critical bug in the geos Debian
 package too, [https://bugs.debian.org/831177 Debian Bug #831177] reported
 by Lucas Nussbaum.

 It looks like the `std::isnan` change from r4169 also needs to be applied
 to `include/geos/platform.h.in` to use that instead of plain `isnan`.
 attachment:gcc6-isnan.patch fixes this issue for the Debian package with
 GCC 6.1.1 from Debian unstable (in addition to the change from r4169).
