What we are seeing in mutt is a segfault if IMAP fails to allocate memory,
the corefile is attached.
It seems that mutt is not aware that the IMAP server closed the connection
with:
* BYE [ALERT] Fatal error: Cannot allocate memory
the stack trace is
{{{
#0 0x080dbda4 in imap_sync_mailbox (ctx=0x83165a0, expunge=1,
index_hint=0xbf8c6bd0) at ../../imap/imap.c:1124
#1 0x0808e349 in mx_close_mailbox (ctx=0x83165a0, index_hint=0xbf8c6bd0)
at ../mx.c:1053
#2 0x08065177 in mutt_index_menu () at ../curs_main.c:1143
#3 0x08082048 in main (argc=1, argv=0xbf8c75f4) at ../main.c:1005
}}}
in imap_sync_mailbox() the idata struct contains a ctx field which is 0x0
and when, at imap/imap.c:1125, this is done:
{{{
if (expunge && mutt_bit_isset (idata->ctx->rights, M_ACL_DELETE))
}}}
mutt crashes because idata->ctx == 0
Cheers
Antonio
