Hi,
I'm the maintainer of RSQLite, the R language binding for SQLite.
Recently, CRAN (the common R archive network) has started running all
R packages with USBAN. This reveals a problem in sqlite.c
(http://www.stats.ox.ac.uk/pub/bdr/memtests/UBSAN-gcc/RSQLite/tests/testthat.Rout)
> library(RSQLite)
> con <- dbConnect(SQLite(), dbname = tempfile())
sqlite/sqlite3.c:63931:5: runtime error: null pointer passed as
argument 2, which is declared to never be null
sqlite/sqlite3.c:63932:5: runtime error: null pointer passed as
argument 1, which is declared to never be null
The block of code that refers to is:
if( p->azVar ){
p->nzVar = pParse->nzVar;
memcpy(p->azVar, pParse->azVar, p->nzVar*sizeof(p->azVar[0]));
memset(pParse->azVar, 0, pParse->nzVar*sizeof(pParse->azVar[0]));
}
So maybe the check should be on (pParse->azVar) ?
(as of version 3.8.6)
