Package: alpine
Version: 2.02-3
Noting this here, although it's an upstream bug and I'll submit it
upstream soon. After disconnecting my machine from the network and leaving
alpine open, it hung with the prompt "Waited 919 seconds for server reply.
Break connection to server?" and the message "[MAIL FOLDER "INBOX" CLOSED
DUE TO ACCESS ERROR]". gdb gives the following backtrace:

According to signal(7), ctime is not safe to be called from a signal
handler (nor, more generally, are malloc or free). Probably debug messages
from signal handler context should not attempt to display the time, or
should use some built-in time implementation that doesn't malloc or care
about timezones, or something.
