2.7-4

It also happens with libc6-i686 purged, in any case, so that's not that:

#0  0xb7e31e21 in strcmp () from /lib/libc.so.6
#1  0xb7de5467 in _nl_find_msg () from /lib/libc.so.6
#2  0xb7de6102 in __dcigettext () from /lib/libc.so.6
#3  0xb7de4ea3 in dcgettext () from /lib/libc.so.6
#4  0xb7e32339 in strerror_r () from /lib/libc.so.6
#5  0xb7dffb44 in vfprintf () from /lib/libc.so.6
#6  0xb7e22bc4 in vsnprintf () from /lib/libc.so.6
#7  0xb7e07275 in snprintf () from /lib/libc.so.6
#8  0x080485f0 in run ()
#9  0xb7f12383 in start_thread () from /lib/libpthread.so.0
#10 0xb7e9663e in clone () from /lib/libc.so.6

I have tried countless time to reproduce it under valgrind with no results.

I have libc6-dbg and that won't do it, what else am I supposed to do?
