Bug #66046 for Archive-Builder:

In Archive::Builder::Archive::_tar(), due to the way Archive::Tar::write() is called (no arguments, meaning return the result as a string) a doubling of the amount of memory in use occurs. When working with input data which results in a large output file (large number and/or size of files), this can result in an out-of-memory condition, especially with 32-bit Perls. I would like to suggest adding a call to Archive::Tar's clear() method, which will allow the Archive::Tar object's data to be garbage collected, as such: # at end of Archive::Builder::Archive, _tar() method: # Get the output my $string = $Archive->write; # free up some memory $Archive->clear; $string ? \$string : undef; }
