Need help on Bus error(coredump)

Vision© · #1 (**permalink**) 02-17-2009

Hi all,

I am quite weak in C but I need to get some work done. Hope someone can help me out. I keep getting this error when i try to run my C application in my HP-UX 10.20 machine.

Some code snippet:

Code:

Month(DBTime) =====This is a function which will return variable "CutOffTime" to be use below
strcpy(DBSecTime, CutOffTime)
sprintf(str, "DBSecTime is : %s\n", DBSecTime);
InputLog(Log, str);

exec sql begin works;
sprintf(str, "DBSecTime is : %s\n", DBSecTime);
InputLog(Log, str);

exec sql select * from tableA where time < :DBSecTime

exec sql commit work;

I am able to print out values of DBSecTime on every sprintf until I reach the sql statement, following which, a Bus error(coredump) will appear.

Hope someone is able to give me some advices. Thanks in advance.

You should include more code, such as the declaration of DBSecTime. And what is this ?

Code:

exec sql select * from tableA where time < :DBSecTime

That's not C code.

Hi otheus, sorry about that, I have included more codes.

Code:

exec sql begin declare section;
char DBSecTime[15];
exec sql end declare section;

Month(DBTime) ===== This is a function which will return variable "CutOfftime" to be use below:
strcpy(DBSecTime, CutOffTime)
sprintf(str, "DBSecTime is : %s\n", DBSecTime);
InputLog(Log, str);

exec sql begin works;
sprintf(str, "DBSecTime is : %s\n", DBSecTime);
InputLog(Log, str);

exec sql select * from tableA where time < :DBSecTime

exec sql commit work;

exec sql select * from tableA where time < : DBSecTime, this is actually a embedded sql statement in my C code. I just find it strange that the 2 sprintf statement was able to run smoothly but not the DBSecTime that was in the sql statement. I have even try to replace DBSecTime in the sql statement with a value like "200812000000" and it managed to got thru too.

Hi vbe, file core return
core: core file from 'Test.exe' - received SIGBUS

Ah. you haven't nul-terminated DBSecTime!! C won\t do that for unless you tell it to.

char DBSecTime[15] = { 0 };
