[Bug 1397666] Re: sshd does not properly initialize libgcrypt

[Pieter H]

thanks for the quick response... well.. it is sort of a clean trusty
install. but.. with the first things being installed are kerberos and
some pam modules ;-) Your remark about the pam module makes sense.

in short.. I installed the debug symbols of packages that interested me.
Installed dbg and setup sshd on a different port. started a new ssh
session, started the debugger and attached it to the process serving my
new session. added a breakpoint on global_init and logged in with the
session.. the breakpoint was hit ;-)

below the backtrace.  so I guess I found the module responsible for
this.. unfortunately I was not able to find any debug packages for
libpam-ccreds (version 10-6)... so how to continue.. is there any way I
can get the debug symbols for this package and narrow down to the
functions being involved? or is this information below enough?
