Source: boost1.67 Version: 1.67.0-17 Severity: serious Control: block 960193 by -1
Changing the icu version changes the libboost_regex ABI. The libboost-regex*-icu* provides untangle icu transitions from boost transitions, but reverse dependencies of libboost-regex1.67.0 in buster depend on libboost-regex1.67.0 not libboost-regex1.67.0-icu63. A build dependency on libicu-dev (<< 64) would prevent accidental recompilation with a more recent icu, avoiding problems if people would install the rebuilt libboost-regex1.67.0 on buster. If wanted I can NMU this change.
