Description Ulrich Grey 2015-05-08 15:47:32 UTC 
I think this is related to the files:

.sylpheed_cache and .sylpheed_mark

in the mail folders.

If I do this in a mail folder ("Inbox" for instance):

rm .sylpheed_*
touch .sylpheed_cache .sylpheed_mark
chflags uchg .sylpheed_*

then mail/sylpheed does not crash, but it is slow showing the contents of a mail folder.

sigbus fix

Hi,

The sigbus is caused by unaligned access:
Program received signal SIGBUS, Bus error.
[Switching to Thread 21c03300 (LWP 100078/sylpheed)]
procmsg_read_cache_data_str_mem (p=0xbfbff5f4, endp=0x217c4335 "", str=0x21fb8844) at procmsg.c:167
167		len = *(__packed const guint32 *)(*p);

a second sigbus is triggered in READ_CACHE_DATA_INT: n = *(const guint32 *)p;

The attached patch fixes that, tested successfully by Ulrich.

Thanks.
