We were seeing the problem also on other ppc64BE:

ppc64 (big endian):
fuzzdata1.db: 0% 10% 20% 30% 40% 50% 60% 70%./fuzzcheck /home/abuild/rpmbuild/
BUILD/sqlite-src-3310100/test/fuzzdata1.db (sqlid=7726,dbid=1): segfault

The issue is cured with the fix, but we still see 3 failing tests with fts4/
fts5:

! fts5matchinfo-15.1 expected: [X'02000000']
! fts5matchinfo-15.1 got:      [X'00000002']

On armv7l, there is another failure in the fuzztests, with and without the 
patch:
sessionfuzz-data1.db: sessionfuzz: ./sqlite3.c:57249: pager_open_journal: 
Assertion `rc!=SQLITE_OK || isOpen(pPager->jfd)' failed.


Kind regards,

Stefan
