Description of problem:

The current official version of sqlite (3100200) defines 'unixCurrentTime' as 0. Programs using this pointer-to-function crash.
E.g. qgis uses this when saving a layer.
gdb shows:

#1  0x00007fffef0c63b3 in sqlite3OsCurrentTimeInt64 (pVfs=0x13237b0, pTimeOut=0x13a96a8) at sqlite3.c:17851
17851       rc = pVfs->xCurrentTime(pVfs, &r);
(gdb) print *pVfs

  xCurrentTimeInt64 = 0x0, xSetSystemCall = 0x0, xGetSystemCall = 0x0, xNextSystemCall = 0x0}

Note the last 4: all pointers-to-function, set to 0x0.

Version-Release number of selected component (if applicable):
sqlite-3.10.2-1.fc23.x86_64

How reproducible:
Always, e.g. by using qgis

Steps to Reproduce:
1. Launch qgis
2. Open an existing project
3. Right-click on a layer and select "save as" --> crash

Actual results:
crash

Expected results:
No crash

Additional info:
sqlite can be patched. If one compiles the current source (sqlite-amalgamation-201602020204) and links to that library, the pointer-to-function is no longer 0 and there is no crash
