A script "[print(1)]; print(2)" should output "12".
However, the compiler had eliminted "[print(1)]" expression
because it is void expression (unused array).
Of course, side-effect should be remained.

th->base_block is information for (a) parsing, (b) compiling
and (c) setting up the frame to execute the program passed by
`eval' method. For example, (1) parser need to know up-level
variables to detect it is variable or method without paren.
Befor (a), (b) and (c), VM set th->base_block by passed bindng
(or previous frame information). After execute (a), (b) and (c),
VM should clear th->base_block. However, if (a), (b) or (c)
raises an exception, then th->base_block is not cleared.
Problem is that the uncleared value th->balo_block is used for
irrelevant iseq compilation. It causes SEGV or critical error.
I tried to solve this problem: to clear them before exception,
but finally I found out that it is difficult to do it (Ruby
program can be run in many places).
Because of this background, I set th->base_block before
compiling iseq and restore it after compiling.
Basically, th->base_block is dirty hack (similar to global
variable) and this patch is also dirty.

Divide big array (or hash) literals into several blocks and
concatetene them. There was a problem that a big array (hash)
literal causes SystemStackError exception (stack overflow)
because VM push all contents of the literal onto VM stack to
make an array (or hash). To solve this issue, we make several
arrays (hashes) and concatenate them to make a big array (hash)
object.

fixes: Bug #2729
a patch from Kazuki Tsujimoto <kazuki@callcc.net>
This problem is caused by changing dfp (dynamic env pointer)
from saved dfp. Saved dfp is pointed env in VM stack. However,
the dfp can be moved because VM copies env from VM stack to
the heap. At this copying, dfp was also changed. To solve this
problem, I'll try to change throw mechanism (not save target dfp,
but save target cfp).
