awk leaks memory on RHEL5_64

[Jeetendra Mirchandani]

Hi,

I have discovered that awk leaks memory on a rhel5_64 box

awk '{if(FILENAME=="file1")interested[$1]=1; else if(interested[$1])print}'
file1 file2



Here file1 is about 40MB in size, with about 500K records. file2 has about
220MM records and is about 9GB in size.

awk process grows to 13GB + in size

$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5 (Tikanga)

$ uname -r
2.6.18-53.1.14.el5

$ awk --version
GNU Awk 3.1.5

$ rpm -q gawk
gawk-3.1.5-14.el5

$ rpm -q glibc
glibc-2.5-12
