[New-bugs-announce] [issue7455] cPickle: stack underflow in load_pop()

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

load_pop() pops a value if the stack length is >= 0. The test is wrong:
if the length is zero, the stack is empty and stackUnderflow() have to
be called.

Example:

  $ ../../python -c "import cPickle; cPickle.loads('0')"
  Erreur de segmentation
