Richard,
I've found a problem that I don't understand. Looking at the case
OP_VerifyCookie, I attempted to output pOp->opcode, which I expected to
equal OP_VerifyCookie. However, it doesn't:
Schema has changed current state = 'db=0025, pOp->opCode=66785672,
db->aDb[pOp->p1].pSchema=02110AB
Richard,
Is it reasonable to say that, assuming:
1. The schema has not changed
2. There is only one connection to the database
that the value of iGeneration should always equal pOp->p3 in
OP_VerifyCookie?

Ok. Possible scenario. I can't prove it, but somebody tell me if this is
what could be going on:
prepare query1
prepare query2
create something -> schema change
query1.step
- schema invalid so recreate
- recreation of schema changes the generation

I really found it this time.
While I was looking over the code changes, I noticed a section of code
dealing with case OP_VerifyCookie:
Inside that section is the following in 3.7.6
if( u.av.iMeta!=pOp->p2 || u.av.iGen!=pOp->p3 ){
sqlite3DbFree(db, p->zErrMsg);
p->zErrMsg = sqlite3DbStr
Let me rephrase that...
I ran this test with a small case. See results below.

Richard, more information for you. I rebuilt the call stack checking

triggering the re-parse which did not do so in the earlier
version.

Question:
If a query has already been prepared with sqlite3_prepare_v2, why would
sqlite3_step need to call sqlite3Prepare, which in turn calls
sqlite3RunParser?

I started looking at yy_reduce, but it looks machine generated. If you
give me some direction I'll see if I can narrow it down further.

Whatever is happening, it appears I can only reproduce it under these
circumstances. I'll continue digging into the procedure tomorrow to see if
I can narrow down where this is coming from.

FYI, I traced the number of calls to sqlite3ResetInternalSchema() on a
smaller set of data. It appears that it isn't the culprit.
Total mallocs: 148,156
Total calls to sqlite3ResetInternalSchema(): 63

What else could trigger a call to sqlite3ResetInternalSchema()? I'm
getting a clear breakpoint tracing back to such innocuous calls as
_sqlite3_step.

I could not use any of the proffered tools for several reasons. After an
inspiration yesterday, I dusted off my C programming skills and started
hacking a pseudo-call stack system into SQLite3.c. I've put the statistics
below for the top couple of call stacks.
Total times _malloc called in test:

I will adjust the realloc tests tomorrow and let you know. The two
routines are unique in the Delphi library unit.
Thanks again for your time and efforts.

Richard,
I don't know if the calls to _realloc will help also, but I've added
tracing for those also. My updated output:

I did this trace through the Delphi IDE and hand copied the call stack.
Unfortunately, I can't give you line numbers, although I could go back and
give you hex offsets from the start of the procedures. These are literally
the first seven call stacks from _malloc after I initiate the trace. I'm
