My company recently completed a commercial, production quality port and
validation of SQLite on GHS Integrity for one of our customers. The database
was stored on NAND flash under WLFS2.

Please get in touch with me directly if you want any more information about
this.

This can be fixed so that the pthread symbols are available to the SQLite
code so that the SQLite thread serialisation can be used. We also defined
SQLITE_OMIT_LOAD_EXTENSION to avoid the dl* symbols.

The exception in the VFS address space is something we saw and is in fact an
Integrity issue not a SQLite issue.
