Assertion failed

Pedro_5 — Tue, 18 Dec 2001 10:44:32 GMT

Hi.

We have a program running on HP-UX 10.20 that throws the next message at run-time:

"Assertion failed: !(fgets(hardwareAddr, (STRLEN-1), fstream) == NULL), file snlui.c, line 1251"

The problem is that sometimes the program works well.

The Oracle version is 8.0.6.

Any ideas?

Pedro.

If you don't have the source code to the program, use "tusc" to obtain a system call trace. This will give you more information on why the fgets is returning NULL - whether it is an end of file condition or a read error. You can obtain tusc from http://hpux.connect.org.uk/

If you have source code, I would recommend removing the assertion from around the fgets and replacing it with something like:

if (fgets(hardwareAddr, (STRLEN-1), fstream) == NULL) {
if (!feof(fstream)) {
perror("fgets");
abort();
} else {
printf("end of file\n");
fclose(fstream);
}
}

Steve

Oops, just noticed you're running 10.20. Use "trace" instead, which is the 10.20 equivalent of tusc. You can get it at the same place.

I don't have the source code to the program. I have used "trace", but I don't have idea why the program fails.

Any suggestions?

Pedro.

Can you post the trace output? If its large just post the last 100 lines or so.
