On an aside...I am still seeing some lmdb issues, even at the most basic
levels. "mtest" is the only thing that's simple enough to run. "mtest2"
for example:

I see nothing like this on our sparc system
-bash-3.00$ uname -a
SunOS igil 5.10 Generic_137137-09 sun4u sparc SUNW,Sun-Fire-480R

What exactly are you running on?

None of the line numbers in your debug output match up with the line numbers in RE24 mdb.c. What git revision are you actually running? Do you have local patches to liblmdb?

(dbx) debug ./mtest2
(dbx) rm testdb/*

In the back-mdb environment, test000 displays similar behavior.
