Hi
I have a crash when running a sqlite based app on solaris machines in 64
bits mode. the crash is actually a bus error when executing an sqlite_exec.
As recommended in this forum ,when running with gdb, I found that the crash
is in this line:
pIndex->azColl[i] = zColl;
This is the stack in gdb:

What i get is a bus error, and it is related to bits alignment for azColl
Type of azColl is char ** e.g. on solaris64 (lp64) it must be % 8
(otherwise one gets SIGBUS, as far as I know...)
this is the pIndex struct content
print *pIndex *pIndex = {
zName = 0x1054931d6 "IDX_OBJ"
nColumn = 2
aiColumn = 0x1054931cc
aiRowEst = 0x1054931b0
pTable = 0x105493418
tnum = 0
onError = '\0'
autoIndex = '\0'
bUnordered = '\0'
zColAff = (nil)
pNext = (nil)
pSchema = 0x1053e8d88
aSortOrder = 0x1054931d4 ""
azColl = 0x1054931bc
}
The address of azColl is 0x1054931bc and it is %4 (but not 8) , i.e.
p (long)0x1054931bc
$1 = 88682940
(gdb) p 88682940.0/8
$2 = 11085367.5
any clue what can cause that ? is there a special build isntruction for
compiling sqlite.c on solaris ?
please advice
