I'm able to reproduce it using 2.05b-17 (latest default) and 3.0-2:
$ bash --version
GNU bash, version 2.05b.0(1)-release (i686-pc-cygwin)
Copyright (C) 2002 Free Software Foundation, Inc.
$ /usr/bin/bash `perl -e "print 'a'x8388600"`
130 [main] bash 2876 cmalloc: cmalloc returned NULL
Segmentation fault
$ bash --version
GNU bash, version 3.00.16(2)-release (i686-pc-cygwin)
Copyright (C) 2004 Free Software Foundation, Inc.
$ /usr/bin/bash `perl -e "print 'a'x8388600"`
6 [main] bash 3496 cmalloc: cmalloc returned NULL
