crash when filling a big buffer

[Daniel Etzold]

Why does this crash?

#include <string.h>
int main( int argc, char** argv ) {
char b[ 16000000 ];
memset( b, 0, 16000000 );
}

gcc crash.cc -o crash

Why does this crash?

#include <string.h>
int main( int argc, char** argv ) {
char b[ 16000000 ];
memset( b, 0, 16000000 );
}

gcc crash.cc -o crash

"crash.cc" has the aroma of c++, anyway,
You have exceeded the limits provided by Standard C.

5.2.4.1 Translation limits
1 The implementation shall be able to translate and execute at
least one program that contains at least one instance of every
one of the following limits:13)

-- 65535 bytes in an object (in a hosted environment only)

13) Implementations should avoid imposing fixed translation limits
whenever possible.

An implementation is not compelled by the Standard to
successfully translate crash.cc.

Because you have exceeded the allowable stack size.
Consult your OS documentation to see how you would change those limits.
