I frequently (but not always) get a crash when I run mtest(x).exe.  It always
works after I delete data.mdb.

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!
