we need more info here ... you neglected `emerge info` for starters ... how do you have vsftp setup such that it's giving you this bad behavior ? re-emerge ftp like this: FEATURES=nostrip CFLAGS='-pipe -O1 -g -ggdb' emerge ftp and then run it through gdb again

Any ideas ?
Hellooooo!!! Who know, where is the bug ?? How fix this bug ?? Please answer.
Created attachment 70640 [details, diff] ftp-dont-strcpy-overlapping.patch try this patch and see if it fixes your segfault
Comment on attachment 70640 [details, diff] ftp-dont-strcpy-overlapping.patch better yet, sync up and emerge ftp-0.17-r6 it is currently KEYWORDS=-* so you'll have to emerge it by hand
THX, it works OK.
thanks, moved into ~arch
