>Description:
>How-To-Repeat:
Perl runs out of memory when using large hashes. Can't be, there is 512MB Ram in the system plus nearly another 2Gig swap.
bash-2.05b$ cat test.pl
#!/usr/pkg/bin/perl
for($outerLoop = 1; $outerLoop<110000; $outerLoop++) {
$HashKey = "A $outerLoop A";
$HashData = "B $outerLoop B";
#Generate larger hash
for($innerLoop = 1; $innerLoop<10; $innerLoop++) {
$HashKey = "$HashKey $HashKey ";
$HashData += "$HashData $HashData ";
}
$MyHash{$HashKey} = $HashData;
}
bash-2.05b$ perl test.pl
Out of memory during request for 5644 bytes, total sbrk() is 132347904 bytes!
