Compiler seg fault

When I go to compile my program two of the files compile fine, then it gets to a third and I get a segmentation fault (linux, it usually means that the program tries to access memory that is not legal for anyone who doesn't work on linux) created by the compiler when trying to compile the third file. Does anyone know what could cause the compiler to do this?

Well without actual versions, error messages, code - what do you want me to say?

The compiler might be running out of memory. How much RAM do you have?

You can compile each source file individually and link them yourself. If a single source file is too big, split it into two files.

On my Windows computer, I had to split up a 40,000 line program (generated by another one of my programs) into 3 files . . . and I have 256 MB of RAM.

Well, I'm compiling on a server, so I'm assuming it has quite a bit of RAM. Also, the file isn't that many lines, < 500.

Oh, sorry, forgot to post what I'm compiling in. I'm using the GCC compiler (g++)
The error:
g++: Internal error: Segmentation fault (program cc1plus)

uh, a stone age OS !!!
frankly do you think that will ever happen on a modern OS ?!?
Virtual memory was invented for some reason

but 40k lines ?!? whoa !
where's what I get with 100k lines in MSVC++ 6

a.c(65536) : warning C4049: compiler limit : terminating line number emission

and gcc compiles the whole file, although it takes about 10 secs

Uh, I don't have 40K lines, that was someone else. I have less than 500 in this particular file

that reply wasn't to you.
Try a different compiler or update your current one.

EDIT:
do this on your command line.

Code:

---

$ gcc -dumpversion

---

I get 3.3.3

Still not seeing any useful information which might help solve the problem. Simply saying gcc isn't enough.

> I have less than 500 in this particular file
Make a copy of it, start hacking out blocks of code and find a small example which duplicates the problem. Post it here.

And make sure you mention the gcc version number as well!

Right, I'm not sure what the version number is (not versed enough in linux to check that). I don't even know where to start "hacking" parts out of the code, since I don't have any indication what is causing the cc1 program to seg fault except that it does it on one particular file.

gcc -v should give you the version of gcc

since you have no idea what is causing the error just remove everything but main() and test

then add a bit at a time until you get the error.
then take everything but that bit out and see if you still get the error.
repeat until you are confident you found which part is to blame.

There is no main, this is just a file that contains a whole bunch of functions. So should I just take out all the functions and see which one is doing it?

gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-42)

> So should I just take out all the functions and see which one is doing it?
Yeah, that'll do for now.
The basic idea is that you post something small here (which crashes your compiler), and we all try it using our compilers to try and work out whether it's your code, your compiler or just randomness in the universe which is the problem.

Well I have no idea what is crashing it, so I guess Ill go through, function by function.

I narrowed it down to one line that crashes the compiler:

Code:

---

actual.score = Score(actual, data);

---

actual is a struct passed by reference to the function, data is also a struct.
I've checked to make sure that score is a member, and it is.
The Score function's declaration looks like:

Code:

---

double Score(AEE addeff, datavar data);

---

and the declaration of the function that this line is in is:

Code:

---

void Create_data(AEE &actual, datavar &data, total_net &net, double fake_st_dev);

---

The AEE struct is:

Code:

---

struct AEE
{
    char name;
    int namelen;
    EE eff[MAX_EFF];
    int size;
    double score, mean, st_dev;
};

---

A sugestion... or not since your gcc is a bit old.. send your source to gcc bugzilla. Let's see if that bug has already, or not, been corrected.

I found that the seg fault occurs because of the function call, not because of the assignment. I changed it a bit so that:

Code:

---

double buffer = Score(actual, data);

---

This causes the compiler to crash still.

I find these statements at odds.

Whoa, thanks. Its supposed to be passed by reference. Missed the '&'.
Thanks!
However, I'm still getting the seg fault.
The declaration was supposed to be:

Code:

---

double Score(AEE &addeff, datavar &data);
