Friends, I build .debs of Go which are used as a dependency for Prometheus debs. Doing code upgrades I started getting a weird panic from the Go linker that I don't see elsewhere on the Internet, and seems different from the cgo bug that caused 1.12.3 to be released today. Below are the relevant logs. Of course, I can't reproduce this with the Go distributed binaries, so I assume I'm missing some sort of build dependency. Just not sure where to look next. Help appreciated!
