 I frequently (but not always) get a crash when I run mtest(x).exe.  It always
 works after I delete data.mdb. 
It's normal. None of the test programs do any error checking, and they are not 
meant to be run. They are meant to be single-stepped under a debugger, and a 
developer is meant to examine the result of each call, manually. If you're not 
an LMDB developer you should just ignore these.

Closing this ITS.
...

 The line causing the crash is listed below.

 rc = mdb_txn_begin(env, NULL, 0, &txn);

 The binary was compiled using mingw gcc 4.6.2.

 I modified the makefile to use -lpthread or -mthreads so it would compile.  Both
 versions would periodically crash.

 Any ideas?

 Thanks!
