Backport changed from 2.5: DONTNEED, 2.6: DONTNEED, 2.7: REQUIRED to 2.5: DONTNEED, 2.6: DONTNEED, 2.7: DONE ruby_2_7 f49355a720afe492ea49809e469dce36a9ea961a merged revision(s) 555bd83a8e8b1e859f698089cbbd9ad938159a0e. ---------------------------------------- Bug #17192: ISeq.load_from_binary can cause BUG if binary is a rbinc-derived https://bugs.ruby-lang.org/issues/17192#change-90342 * Author: wanabe (_ wanabe) * Status: Closed * Priority: Normal * ruby -v: ruby 3.0.0dev (2020-09-25T22:52:04Z master 137fa5b27e) [x86_64-linux] * Backport: 2.5: DONTNEED, 2.6: DONTNEED, 2.7: DONE ---------------------------------------- The following command can cause BUG. ``` $ ruby -e 'print RubyVM::InstructionSequence.of(1.method(:abs)).to_binary'|ruby -e 'RubyVM::InstructionSequence.load_from_binary(ARGF.read)' -e:1: [BUG] ibf_load_builtin: table is not provided. ruby 3.0.0dev (2020-09-25T22:52:04Z master 137fa5b27e) [x86_64-linux] -- Control frame information ----------------------------------------------- c:0003 p:---- s:0011 e:000010 CFUNC :load_from_binary c:0002 p:0026 s:0006 e:000005 EVAL -e:1 [FINISH] c:0001 p:0000 s:0003 E:001910 (none) [FINISH] -- Ruby level backtrace information ---------------------------------------- -e:1:in `<main>' -e:1:in `load_from_binary' -- C level backtrace information ------------------------------------------- [0x5635c8378d2e] /home/wanabe/.rbenv/versions/master/bin/ruby(rb_bug+0xe9) [0x5635c817641c] ../../error.c:686 [0x5635c817b772] /home/wanabe/.rbenv/versions/master/bin/ruby(ibf_load_iseq+0xf3) [0x5635c83de093] ../../compile.c:11898 [0x5635c83de18e] (snip) ``` I think that `ISeq.of` should raise some kind of exception on the case. Or `ISeq.load_from_binary` may raise an exception. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
