Package: release.debian.org Severity: normal X-Debbugs-CC: smr@debian.org gcc5, icu are now build with libstdc++11 abi, and so is boost1.58. It's time to switch boost from 1.55 to 1.58. Otherwise libraries that are getting gcc5 soname bump that use boost as well, may get incompatible abi as a whole. I have boost-defaults upload ready, may I upload it? Regards, Dimitri.
