This Mac Tk bug was supposedly fixed in 2016 or 2017. Details are in the
following Tk ticket.

The previous URL to the Tk ticket no longer works. In case the above URL also
goes bad, the id number
Tom Goddard added the comment:
Ok I reported this as a Mac Tk bug and gave a very simple way to reproduce it.

I've seen this crash about 50 times in the UCSF Chimera molecular visualization
package, same traceback, and it is caused when a tooltip is raised, but not
from IDLE. The key observation is that it only happens on dual display systems
where the second display
Tom Goddard added the comment:
More testing shows that this Mac Tk crash with dual displays only happens when
the second display is partly or entirely above the primary display in the Mac
display system preferences. An attempt to show the tooltip on the second

In Python 2.7, random.seed() with a string argument is documented as being
equivalent to random.seed() with argument equal to the hash of the string
argument. This is not the actual behavior. Reading the _random C code reveals
it in fact
Tom Goddard godd...@cgl.ucsf.edu added the comment:
I agree that having such large Python code files is a rare circumstance
and optimizing the byte-code compiler for that should be a low priority.
Thanks for the cpickle suggestion. The Chimera session file Python code
is mostly large nested
New submission from Tom Goddard godd...@cgl.ucsf.edu:
Bytecode compiling large Python files uses an unexpectedly large amount
of memory. For example, compiling a file containing a list of 5 million
integers uses about 2 Gbytes of memory while the Python file size is
about 40 Mbytes. The memory
