do we know if these are legitimate failures or not? the build system could be hardcoded to do a 64bit build

I have no idea: I couldn't figure out why it's crashing.

The tests are passing in 19.09. I bisected and 183c6b9 came up.
I still have no idea how a test could crash python.

I managed to run the tests in gdb and got a backtrace:

The test is really crashing the python 2.7 interpreter, specifically the garbage collector.
A crash should never happen in theory, unless you are doing something deliberately or running some C library. This is either a bug in python 2.7 or in some C code that's tricking the interpreter into freeing protected memory. This seems to be the only library around: _speedups.c.

I showed upstream the trace and it appears the test suite is running out of stack space.
Disabling the tests on 32bit system should be the right thing to do.
