Full_Name: Joseph Gentle Version: Gitorius master 2d6aed7 OS: MacOS URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (50.1.123.217) Using the latest version of lmdb in https://gitorious.org/mdb/mdb (2d6aed7), I went into the liblmdb directory, ran make then ran the tests. All tests crash with Segmentation Fault. Problem can be reproduced compiling with gcc or clang, and gcc on linux.
