I’m having a strange behavior with an application, it segfaulted before every time while running it after the first error which happened after I closed it (after first use)
But then I by accident missed the – while trying to run it in debugging mode. So it kinda looks like this “./nameapp d” and that puzzles me, any insight or guess what is going on there? What difference does that make?

Cause after doing this it suddently worked again without error where as it segfaulted every single time before that. Could be random behaviour but others with the same problem seem to say it fixed it for them too.

Invoking “ps gave me “segmentation fault”. Managed to got rid-off the problem by upgrading “procps”.

Segmentation Fault may also occur if disk is running out of free space!

Hello All Forum members,

I am in dire need of help please. Can some one help me solve this segmentation problem ?

I have part of the code like this. I have tried to put displays around to track down the flow as follows:

LET GetInput = TRUE
WHILE GetInput
display ” Inside infield manno 1 ”
display “GetInput = “, GetInput
sleep 5
INPUT w_manno,
w_surname
WITHOUT DEFAULTS
FROM manno,
surname

AFTER FIELD manno
display ” Inside infield manno 2 ”
sleep 5
IF w_manno ” ”
AND w_manno IS NOT NULL
THEN
SELECT COUNT(*)
INTO w_cnt

The second display is not coming. I can’t put a display just after the INPUT command or as I am getting a syntax error.

I have also tried the following:

LET GetInput = TRUE
WHILE GetInput
display ” Inside infield manno 1 ”
display “GetInput = “, GetInput
sleep 5
INPUT BY NAME manno,
surname
WITHOUT DEFAULTS

But still I don’t seem to get what is going on. How do control the cursor to placed in the input field ?

Thanking you in advance.

Suddenly my software started giving a Segmentation Fault.

Language C, O/S: Linux.

Following is a (pseudo) code snippet:

1. x=strtok(y,”:”);
2. if(strlen(x)>0) { do_something; }

Line 2 would cause a Seg Fault. I would guess it should at least give me a false result.

Hence I changed the code to:

2. if(x != NULL) if(strlen(x) > 0) { do_something; }

Note: you cant do if(x != NULL && strlen(x) > 0) as the strlen woud cause a SegFault (GP fault in Windows, i guess).

Regards.
