Package: libtext-unaccent-perl
Version: 1.08-1.2+b1
Severity: grave
The most useful method of Text::Unaccent seems to cause a segmentation
fault (which was not the case a few weeks ago):
$ locale
LANG=C
LANGUAGE=
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=C
$ perl -MText::Unaccent -e 'print unac_string("utf-8","a")'
Segmentation fault
$
I tried various locales, to no avail. I also tried changing "utf-8" to
uppercase and/or removing the dash. I also tried rebuilding against
current perl, thinking maybe there was an ABI change.
After installing the debug packages, here's the backtrace I get in gdb:

I don't know whether the bug lies in libtext-unaccent-perl, in perl
itself, or in libc6. Feel free to reassign accordingly :-)
