[sqlite] met "ARM7TDMI raised an exception,data abort" when executing sqlite3Parser() in ARM environment

[Sarah]

Hi,all

During the execution of a test program in an embedded environment, 
after it goes into 
sqlite3_exec()-->sqlite3_prepare()-->sqlite3RunParser(&sParse, zSql, &zErrMsg),
the debugger pops "the ARM7TDMI raised an exception,data abort" when the 
following sentence is executed(bold and underlined):

...
abort_parse:
   ...  
   sqlite3Parser(pEngine, TK_SEMI, pParse->sLastToken, pParse);
   ...

After "data abort" happens, the debugger stops at assembly languages like 
this(pointed by an arrow):
    ...
    [0xbc38]   pop      {r3-r5}
    [0xbc08]   pop      {r3}
    [0x4718]   bx       r3
    [0x6868]   ldr      r0,[r5,#4]
    [0x1c29]   mov      r1,r5
    [0x2800]   cmp      r0,#0
    [0xd018]   beq      0x42fc4  ; (__Heap_Alloc + 0x5a)
--> [0x6802]   ldr      r2,[r0,#0]
    [0x42a2]   cmp      r2,r4
    [0xd311]   bcc      0x42fbc  ; (__Heap_Alloc + 0x52)
    [0x1c23]   mov      r3,r4
    [0x6802]   ldr      r2,[r0,#0]
    ...

When I trace into sqlite3Parser(),it seems like the error is caused by 
"yy_reduce(yypParser,yyact-YYNSTATE);"

My test program is like this: 
{
 char * database = ":memory:";
 sqlite3 * db;
 
 sqlite3_open(database, &db);
 
 sqlite3_exec(db, "create table myt(age smallint)", NULL, NULL, NULL);
 ....
}

sqlite3_open() runs successfully.
And CPU type is ARM7TDMI, no operating system is used, such as linux.

I'm totally confused. Please help me diagnose this error.
Any little help will be appreciated.
