For me, https://people.debian.org/~sthibault/hurd-i386/installer/cdimage/daily/debian-sid-hurd-i386-NETINST-1.iso (Jan 26, 2021) have the following problem:
libsource-highlight4v5 depends on libboost-regex1.71.0-icu67 which ... is not installed -> leaving unconfigured gdb depends on libsource-highligh4v5 ( >= 3.1.9 ) which is not configured -> leaving gdb unconfigured so bootstrap-base failed with error code 1
