There's another GPL'ed awk there, called mawk.

|| $ time awk -f mc.awk mtrace
||          0          0
||          1       5898
||          2      66407

||
|| $ ls -l `which gawk nawk mawk`
|| -rwxr-xr-x    1 root     root       316530 Aug 11  2002 /bin/gawk
|| -rwxr-xr-x    1 root     root       106352 Jan  9  2003 /opt/bin/nawk
|| -rwxr-xr-x    1 root     root        94680 Jan  9  2003 /opt/bin/mawk
||
|| $ ls -l mtrace
|| -rw-r--r--    1 adi      adi      16956443 Nov 17 01:49 mtrace
||
|| where mc.awk is a silly script like that:
||
|| BEGIN { FS="[ \t()]+" }
|| /malloc/ { sz[$5]++ }
|| END { for(i=0; i<7; i++) printf "%10d %10d\n", i, sz[i] }
||
|| and mtrace contains lines of the form:
||
|| xxxx: xx.c:130	malloc	0x0805e3d8 (48)
|| xxxx: xx.c:135	free	0x0805e1f0
|| xxxx: xx.c:1635	malloc	0x0805e458 (2)
|| xxxx: xxxx.c:7183       realloc 0x08081de0 => 0x08081de0 (4)

And it seems not to have some of gawk's bugs:

|| $ echo | gawk 'function p() { print "hi" } BEGIN { gsub(/a/, p()) }'
|| $ echo | nawk 'function p() { print "hi" } BEGIN { gsub(/a/, p()) }'
|| hi
|| $ echo | mawk 'function p() { print "hi" } BEGIN { gsub(/a/, p()) }'
|| hi
