If this is going to take some time can we back out the test (...or the plugin? :/) so that any new errors in i386 are immediately visible? Red lines are bad for our quality and detection abilities.

And just in case anybody else tries searching for it with the same string I did:, this is failing the qa/workunits/erasure-code/encode-decode-non-regression.sh script.

  • valgrind is happy
  • the bug disapear when adding print statements in some places
  • the bug disapear when the code is not optimized and shows up when the code is -O2 or -O3
  • the bug stays when running gdb but introspection is not possible because all variables are optimized out

With non optimized code on i386 (or on amd64):
