    This is a resource limit problem.  Try increasing your data segment size
    with `ulimit -d'.

Hmm -- I've already got `ulimit -d' as `unlimited'.

For completeness:

$ bash -c 'ulimit -a; . bug-case'
core file size        (blocks, -c) 0
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 1024
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) 8192
cpu time             (seconds, -t) unlimited
max user processes            (-u) 3839
virtual memory        (kbytes, -v) unlimited
252 is OK
253 is OK

malloc: /build/packages/bash/bash-2.05b/subst.c:3371: assertion botched
realloc: start and end chunk sizes differ

$

where `bug-case' tries to process-substitute as many as 254 processes
in one command.
