ASM help

[CrowbarOfDeath]

For some reason I get a segmentation fault whenever I try to use strings in assembly. I even got the error when I did just this:

main() {
__asm__("
.string \"foo\"
");
}

I'm using GCC 3.0.1 to compile this and I just don't understand why it's doing this. Any suggestions?

-Thanks

well, considering I haven't used ASM in ages, nor do I remember much about it, I'm gonna give it a shot. No one else has responded yet, so here we go.

do you have to move the stack? does a string require you to add each character to the stack before you do anything with it? &lt;/long shot&gt;

Is it maybe putting the "foo" into memory at the current instruction pointer spot, or something? "Is it trying to execute your data?", is what I'm trying to ask.

Try putting a label after the .string line, and a jump to that label before it.

I believe you can use local variables in inline assembly, too (though maybe not with gcc -- I know you could with Borland Turbo C, but that was a while ago, and for DOS). You could try putting all your data in local variables, outside the ASM section.
