uncaught exception of type std::bad_alloc
Reported by Dave Eckhardt | July 16th, 2014 @ 10:44 PM
I am evaluating MailMate because Mail.app can't deal with a
large
IMAP account because it can't ignore non-subscribed folders.
MailMate worked ok for a day or so but then crashed with
"uncaught
exception of type std::bad_alloc". I am nervous because it
looks
like MailMate is a 32-bit application and according to the
crash
dump the address space looks pretty full... the region
type/size
list looks like this:

The mailboxes I'm subscribed to contain around 200K messages. Is
this a
case of "sorry, bub, you are hopelessly large"?
If so, is a 64-bit version on the horizon (or a way to consume
less memory
per message)? I guess 3G/210000 = 15KB, so maybe MailMate requires
enough
memory to fit all headers into RAM at once?

Depending on your hardware, 200K should not be hopeless. I know a few users have 500K+ messages. But I recommend staying in the 50K-100K range for now.
Yes, part of the problem is 32 bit, part of the problem is MailMate using a lot of memory. I have an experimental (unreleased) 64 bit version of MailMate in the works, but it currently uses even more memory and I need to do more optimizations before releasing it. I'll track progress on the 64 bit version in this ticket.
If you are using r3905 (About window) then hold down ⌥ when clicking “Check Now” in the Software Update preferences window. Newer test releases include some memory related fixes.
Thanks for trying out MailMate.

Indeed moving from 32-bit to 64-bit means that all pointers get larger,
so more memory is consumed. But the upside is that the address space
becomes (effectively) infinite.I will try the prerelease version.

This old request for a 64 bit version was somehow never closed. Doing it now.
