394 | Your kernel limits the data section of your programs to $maxdsiz Mb, | |
395 | which is (sadly) not enough to fully optimize some parts of the | |
396 | perl binary. I'll try to use a lower optimization level for | |
397 | those parts. If you are a sysadmin, and you *do* want full | |
398 | optimization, raise the 'maxdsiz' kernel configuration parameter | |
399 | to at least 0x08000000 (128 Mb) and rebuild your kernel. | |
