Dear all, since upgrading Ruby from 1.8.6.287 to 1.8.7.72, and recompiling PL/ruby 0.5.0, functions written in PL/ruby may ignore their given parameters and instead compute with undefined values, providing nonsense results. The test-suite provided with PL/ruby will show the problem. Upgrading to PL/ruby 0.5.3 does not solve the problem, but that version seems to detect the problem and raise an error. I have figured out how the problem appears, but do not understand why it appears or where exactly the cause is. The problem seems related to the way PL/ruby uses a Ruby function named rb_block_call. That function will only be used when detected during compilation of PL/ruby. While this was not the case with Ruby 1.8.6, it is with Ruby 1.8.7. So, a workaround to get the applications operative is simply to suppress the detection of that function. It is unclear if the actual problem is in Ruby or in PL/ruby. It it also unclear what this function rb_block_call is good for or why it did appear with Ruby 1.8.7. The author of PL/ruby has been contacted, but did not answer.
