The test will call a Python subprocess at a random moment and verify that
GP/Pari shuts down. But depending on timings I get two different outputs:
Either
{{{
An exception has occurred, use %tb to see the full traceback.
SystemExit
sage:
Exiting Sage (CPU time 0m0.02s, Wall time 0m0.11s).
Exiting spawned PARI/GP interpreter process.
}}}
or
{{{
Traceback (most recent call last)...
TypeError: 'int' object is not callable
Exiting Sage (CPU time 0m0.36s, Wall time 0m0.38s).
Exiting spawned PARI/GP interpreter process.
}}}
But the doctest
{{{
sage: str(P.stdout.read()) # long time
'...Exiting spawned PARI/GP interpreter process...'
}}}
matches only the former because of the somewhat convoluted quotation
rules:
{{{
sage: repr("my 'foo' bar") # output starts with single quote
'"my \'foo\' bar"'
sage: repr("my foo bar") # output starts with double quote
"'my foo bar'"
}}}
