New submission from Torim:

If invoking pydoc either from a system shell or as a help() method in an 
interactive Python interpreter, it crashes with SIGSEGV signal at exit.
It crashes only with larger documentation contents, smaller do work as expected.

Example with numpy module docs:
1. launch Python interactive interpreter with `python'
2. type `import numpy'
3. type `help(numpy)' # large help, displayed by PAGER environment variable or 
`more' if missing
4. press `q' to quit the help
5. SIGSEGV "Segmentation  fault" received, python interpreter crashes

Note: if you move in a documentation at the end (last line), you can then 
escape (quit) anywhere without a crash
