It seems more than just coincidence that it only fails on 32 bit architectures. I prepped the cxxtools 3.0 sources and ran this on a x86-64 host (easier than finding an armv7 or i686 host): $ ./configure CC="gcc" CFLAGS="-m32" CXXFLAGS="-m32" LDFLAGS="-m32" $ make $ tools/cxxtz -z Europe/Berlin '2018-11-07 13:00:05' 2018-11-07 13:53:33 LMT 0 so that reproduces the bug. I would say this is an upstream bug and you should report it to them. They should be easily able to reproduce it following the steps above on any x86-64 host.
