informix ESQL SAVEPOINT 问题

[qq_35393519]

/*
创建保存点
保存点名字 poitname
*/
int savepoit()
{
printf("设置保存点");
EXEC SQL SAVEPOINT poitname;
printf("设置保存点");
if(sqlca.sqlcode)
{
printf("设置保存点失败[%d]", sqlca.sqlcode);
strcpy(g_pub_tx.reply, "S081");
return(-1);
}
#if 0
$savepoint poitname;
printf("设置保存点2");
if(sqlca.sqlcode)
{
printf("设置保存点失败[%d]", sqlca.sqlcode);
strcpy(g_pub_tx.reply, "S081");
return(-1);
}
#endif
return 0;
}
每次调用都产生core文件，为何：
Type 'help' for help.
[using memory image in core]
reading symbolic information ...
