Bug#205328: Dynamically linked programs segfault too
Hi,
I've been hitting the same bug today : after a glibc upgrade, some programs
are segfaulting. The programs concerned are :
- consolechars
- citrix ica client
(both are dynamically linked)
>From what I can tell (but I'm no expert in the field) the backtrace (at the
end of this mail) don't show anything nss related, and the backtrace ends in
glibc (not linked program).
I really think that a glibc upgrade should really try not to break previously
compiled applications, whether or not they are proprietary, /usr/local/bin,
statically or whatever.
It would be nice to have some patch on glibc, or at least some workaround for
this problem.
