Thread: c++ illegitimate seg. fault

so before run program like...

code:

int main () { 	int a[400000]; 	int b[400000]; 	int c[400000]; 	int d[400000]; 	int e[400000]; 	//int f[400000];  	system("free"); 	return 0; }

i typed free in terminal see how muce space have says...

code:

             total       used       free     shared    buffers     cached mem:       1018324     566952     451372          0      21348     238816 -/+ buffers/cache:     306788     711536 swap:      2980016          0    2980016

and program ( system("free"); ) returns

code:

             total       used       free     shared    buffers     cached mem:       1018324     566912     451412          0      21360     238760 -/+ buffers/cache:     306792     711532 swap:      2980016          0    2980016

so should have enough free space for...

code:

int main () { 	int a[400000]; 	int b[400000]; 	int c[400000]; 	int d[400000]; 	int e[400000]; 	int f[400000];  	system("free"); 	return 0; }

but segmentation fault. ideas?

all large arrays define go on stack. maybe you're running out of stack space?
