Package: slrn
Version: 0.9.8.1pl1-26
Severity: important
I've upgraded my sid-based notebook last week and I'm running into problems
caused by the charset fallback patch. I'm regularly using "x" to remove
all non-tagged read articles from the article list and slrn segfaults
every 5-7th time.
One article which can reproduce this all the time is an article from
debian-release about glibc time zone changes. I'm attaching a backtrace:
(gdb) bt
#0 0xb7d0192d in free () from /lib/tls/libc.so.6
#1 0xb7efcb11 in SLfree () from /lib/libslang.so.2
#2 0x08050069 in free_header (h=0x86213a8) at art.c:477
#3 0x08055317 in art_xpunge () at art.c:6881
#4 0x0807a7c2 in main (argc=1, argv=0xbfcd39e4) at slrn.c:1786
(gdb) up
#1 0xb7efcb11 in SLfree () from /lib/libslang.so.2
(gdb) up
#2 0x08050069 in free_header (h=0x86213a8) at art.c:477
477 slrn_free (h->from);
(gdb) print h->from
$1 = 0x8623560 "Aurelien Jarno <[EMAIL PROTECTED]>"
(gdb)
I've read through the patches and the fact that h->from caused the crash made
me wonder, if the change from Bas in 0.9.8.1pl1-25 may be the cause:
| * Added fallback charset patch from Bas Zoetekouw and documented the new
| feature in NEWS.Debian. (closes: #403781, #406210)
So I backed out patch 302 and after that I no longer see crashes.
I suppose it's some kind of memory corruption. I don't have prior
experience with the slrn code base and lack the time to dig further
for the cause. Bas, could you have a look? I'd be happy to test patches.
The segfaults are very frequent for my usage pattern (every few minutes)
and quite annoying. I'm running an X-less environment with a plain
fbcon console. (Which could make a difference, I'm not sure)
Cheers,
Moritz
