Hey guys,

We are using LMDB 0.9.19 in our Android project and sometimes we are getting SIGBUS in mdb_page_touch(). We can't reproduce this issue on our side but we have plenty of crash reports from our users (about 400 daily):

SIGBUS libLMDBAndroid.so.mdb_page_touch ( mdb .c :2412) libLMDBAndroid.so.mdb_page_search ( mdb .c :5610) libLMDBAndroid.so.mdb_freelist_save ( mdb .c :3128) libLMDBAndroid.so.mdb_txn_commit ( mdb .c :3606)

This is probably a platform specific issue because 95% of crashes happened on Android 7.0.

I would greatly appreciate if you help to shed a light on this - any ideas what might goes wrong or what might cause such an issue.

Thank you, Sergey
