Sporadic crashes with 1.4.18

[mark@…]

We're experiencing sporadic crashes since upgrading from 1.4.16 to 1.4.18. Here's our current backtrace:

(gdb) bt

(gdb)

We've recompiled with CFLAGS='-ggdb' and are hoping that will provide line numbers for the next time it crashes. In the mean time I'm filing this ticket on the off chance that someone recognizes something that changed in this release that could lead to this crash.

There have been some changes, but without more information i don't see how we could find the bug. Closing as worksforme until more information is provided.
