>Description:
Compiling lib/isc/sha1.c results in:

 gcc -g -O2 -I/export/raid2/local/build/bind-9.1.2 -I./unix/include -I./pthreads/include -I./include -I./include -D_REENTRANT -W -Wall -Wmissing-prototypes -Wcast-qual -Wwrite-strings -c sha1.c  -fPIC -DPIC -o .libs/sha1.lo

cc1: Cannot allocate 131072 bytes after allocating 1565507584 bytes

This is from the bind-9.1.2 tarball off isc.org

Compiling with -O has similar results, compiling without optimizations works fine
