--- Comment #16 from Adriaan de Groot <adr...@freebsd.org> --- I've been debug-chasing this for a few days in an 11.2 VM. The goal is to allow genericbearer to load -- that is, the environment-variable workaround should not be necessary. As Ting-Wei Lan pointed out originally, everything looks like memory corruption **somewhere**. - removing the call to get the interfaceFromIndex(0) fixes the problem - I found a spot in QNetworkInterface where adding qWarning() << "foo" fixes the problem When build WITH_DEBUG=yes I get crashes (SEGV), rather than unresolved symbols: more hint that it's memory corruption. In any case: *because* this is corrupting memory from a Qt-internal method that is listing network interfaces, I would like to fix the root cause rather than working around things. -- You are receiving this mail because: You are the assignee for the bug.
