April 22, 2005 [memory allocation] system freezing? | ||||
---|---|---|---|---|
| ||||
On my win98 system this D program frozed the system. To watch the freezing the program can be given an upper bound for normal growing. When reaching this upper bound the growing will be done element by element. On win xp pro I have not reached that critical point or it might not even exist because win98 was flawed. <code> private import std.c.stdio, std.conv; class C{} C[] a; void main(char[][] args) { int delta= 100000; while(1) { try{ if( args.length>1 && a.length >= toInt(args[1])) delta= 1; a.length = a.length + delta; fprintf(stderr,"%d ", a.length); } catch { printf("Allocated array of length %d.\n", a.length); break; } } } </code> |

On linux the programm was killed without entering the catch block.
