I've gone a little bit into the rabbit hole that = is BFD ld, but the bug does not "jump out" at me. So fixing it is likely not trivial. We could: 1) Patch out the error message in BFD ld (possibly only on stable/11) 2) Spend time to figure why BFD ld is choking on this .eh_frame section, ge= t a fix, submit it upstream, merge it downstream, etc 3) Add -fno-asynchronous-unwind-tables to lib/csu in general 4) Add -fno-asynchronous-unwind-tables to lib/csu/i386 only 5) Add -fno-asynchronous-unwind-tables to lib/csu/i386 only, and only on stable/11 My preference would be for 5). Note that we'd need to MFS any fix to releng/11.4 too. --=20 You are receiving this mail because: You are the assignee for the bug.=
