ko1 c4bc9b5758 * iseq.c, vm_eval.c: set th->base_block properly. ... 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. * bootstraptest/test_eval.rb: add a test for above. * internal.h: remove unused decl. * iseq.c (rb_iseq_compile_with_option): add base_block parameter. set th->base_block before compation and restore it after compilation. * ruby.c (require_libraries): pass 0 as base_block instead of setting th->base_block * tool/compile_prelude.rb (prelude_eval): apply above changes. * vm.c, vm_eval.c: ditto. * vm_core.h: add comments. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36179 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2012-06-22 09:32:56 +00:00
