- Subject: fixing heap_chunk_in_mb to 512MB doesn't work
As far as I have understood allocation is limited to 128 MB
in cygwin 1.3.12 but one can increased this limit by setting
heap_chunk_in_mb registry key.
I tried to fix this value to 512 Mb using :
regtool set '\user\Software\Cygnus Solutions\Cygwin\heap_chunk_in_mb'
512
But when I compile this little test program it fails (Aborted (cored
dumped)):
#include <iostream>
using namespace std;
int main(){
char * tab_ptr = new char [256 * 1024 * 1024];
if ( !tab_ptr ) {
cerr << "Malloc failed\n";
exit(1);
}
delete tab_ptr;
return 0;
}
Thanks for your help
