did that and it seems the problem is in the loop that does:

foreach my $row (@$data)
{

     # To construct fmgroids.h and fmgrtab.c, we need to inspect some
     # of the individual data fields.  Just splitting on whitespace
     # won't work, because some quoted fields might contain internal
     # whitespace.  We handle this by folding them all to a simple
     # "xxx". Fortunately, this script doesn't need to look at any
     # fields that might need quoting, so this simple hack is
     # sufficient.

...
}

it does after around 1050 iterations of that loop at it seems to leak 
exactly 240kbyte per iteration which sums up to around 250MB in total 
for the process...
