bzr stacktrace with MemoryError

[Mark A. Hershberger]

This may be the same as Bug #153749, but I'm reporting it new. I have a copy of the bzr tree giving the error if it is needed.

I have an strace that I'll attach.

From .bzr.log:

Hi Mark,

It looks as this is an open source project, so could you attach
the .bzr/checkout/dirstate file that is broken. Also if you
disable the c extensions as described in

https://bugs.launchpad.net/bzr/+bug/186014

it would help to know whether it is the same error.

Is there any chance that this was caused by a power failure
or similar?

Thanks,

James

oops, attached my dirstate to bug #186014. Will reattach here.

it is /possible/ this is caused by a power failure. I'm not sure what I was doing the last time I used the checkout before this happened. Still, it seems unlikely.

with c extensions disabled:
