Hi,
Can anyone tell me why this script file.c and file.h causes a core
dump when it is compiled and run?
Any help is appreciated.

Try to use less stack. Probably you are going beyond what
you are allowed.
Look at

BTW, C is not a scripting language. Using 'script' in this context is
likely to earn you sneers, so you might not want to do that. In any case
#define KELEM 500
#define KVALS 200000
#define IBFLEN 50000
[...]
int main() {
[...]
int IBUFF[IBFLEN];
char CNAMES[64][KELEM];
char CUNITS[24][KELEM];
char CVALS[80][KVALS];
float VALUES[KVALS];
int KTDLST[KELEM];
int KTDEXP[KELEM];
int KSEC0[8];
int KSEC1[40];
int KSEC2[64];
int KEY[46];
int KSUP[9];
int KSEC3[4];
int KSEC4[2];
char ID[8];
The limits on arrays guaranteed to be supported is much smaller than you
are attempting. Even worse, you are trying to allocate them as auto
variables. Learn to use dynamic allocation or, possibly, static arrays.
Your subject line is completely off base: printf() has nothing to do
with your problem. And splitting the content of your post between
subject line and body of the message is silly. If it's worth saying,
it's worth saying in the body of the message.
return 1;
1 is not a portable value for return. Worse, you are using this for
successful completion. We know that 0 is one of the defined values for
successful completion, the other being EXIT_SUCCESS.

I am not sure that I agree. Exhaustion of automatic storage is
not an event that a C program can detect and recover from.
Exhaustion of dynamically allocated storage, on the other hand,
is.

That's true. If you're writing the kind of program where dealing
cleanly with that is important, it would certainly make sense to
prefer malloc().

Thanks everyone for your comments, critiques, and advice.
I am not a programmer so I don't do this very often and hence the
rookie mistakes.
Dynamic allocating of memory works. I am grateful :)

Does anyone have a problem with Apache2 crashing after executing a PHP

anywhere except at the start of the file, APache will crash. Can anyone
explain to me why? I don't want session_start to be at the start of the

has to happen after the declaration of custom session methods.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
