The patch in the previous message is in fact the cure for the failing functionality on x86_64. By switching the patch on and off in ifconfig/system/linux.c I can reproducibly reintroduce and resolve the error at will. The previous comment on strange name strings was a false negative, since it was caused by an incorrect message in a printf statement I had introduced in "ifconfig/options.c". The purpose was for tracking the bug down. Sorry for that noise! The patch is valid, though. Mats E A
