If no one else is actively working to fix this annoyance, I'll see what I can do. For me, it's mostly a matter of finding the time to download the source package and its dependencies, build a debug version with symbols in it that "gdb" can use, and then *maybe* figure out the best way to code around the unaligned access. If anyone else has the time and would like to have a go at it, the following two links might be useful: https://wiki.gentoo.org/wiki/Project:Alpha/Porting_guide#Unaligned_accesses https://www.redhat.com/archives/axp-list/2000-May/msg00151.html (Yes, the problem has been around at least as long as the alpha architecture :-) ). Michael Cree et al.: do we have a working "gdb" on alpha these days? I seem to recall brokenness there in the not-too-distant past. --Bob
