Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: koenig@linux.de QAContact: qa@suse.de Found By: --- Blocker: --- "getent aliases key" crashes for exactly one aliases record in our nis map. this crash shows up on *all* suse version from 9.0 to 11.1 and 11.3, plus sles10sp1/sp3 and sles11sp0 (and may other linux distros). where can I get glibc-debuginfo and -debugsource packages for either 11.1 or 11.3 64bit current glibc package? this is the key/value data of the record which triggers the crash from "ypmatch -k xxxxxxxxxxxxx-xxx aliases" (all letters replaced by 'x' -- only one non-letter '2' included): key: xxxxxxxxxxxxx-xxx value: xxxxxx,xxx,xxxx,xxxxx,xxxxx,xxxx,xxxxxxx,xxxxxxxx,xxxxxxx,xxxxxxx,xxxxxxx,xxxx,xxxxxxxx,xxxxx,xxxxx,xxxxx,xxxxxxx,xxxxxxx,xxxxxxx,xxxxxxx,xxxxxx,xxxxxx,xxxxx,xxxxxx,xxxxxxx,xxxxxx,xxxxxxx,xxxx,xxxx,xxxxx,xxxxxxx,xxxxx,xxxxx,xxxxx,xxxx,xxxxx,xxxxxx,xxxxxxxx,xxxxx,xxxxxxx,xxxxxx,xxxxx,xxxxxx,xxxxxx,xxxx,xxxxxxx,xxxxxxx,xxxxx,xxxxxx,xxxxxxxx,xxxxxx,xxxxxx,xxxxxxxx,xxxxxxx,xxxxxxx,xxxxxx,xxxx,xxxxxxx,xxxxxxx,xxxxxxx,xx,xxxxxx,xxxxxx,xxxx,xxxxx,xxxxxxxx,xxxxxxx,xxxxxx,xxxx,xxxxx,xxxxxxxx,xxxxxx,xxxxx,xxxxxxxx,xxxxxxxx,xxxxxxxx,xxxxxxx,xxxxxxx,xxxxx,xxxxxx,xxxxxx,xxxxxxx,xxxxx,xxxxxxxx,xxxxxx,xxx2,xxxxxx,xxxxx,xxxxx,xxxxxx,xxxxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxxx,xxxxxxx,xxxxxx,xxxxxx,xxxxxxx,xxx,xxxxxxx,xxxx,xxxxxxx,xxxxxxxx note that this is not the largest record in our aliases map (only 727 chars vs. 773 chars for the longest entry) but it contains the largest number of names (105 for this record, 86 names work in another record with 594 chars, the 773 chars record only has 28 entries). here are crash log and valgrind info for suse 11.1 x86_64:
