[issue5614] Malloc errors in test_io

[Ronald Oussoren]

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:

What's more annoying: the error goes away while running in a debugger.

The issue happens at least in tes_constructor:

test_constructor (__main__.CBufferedWriterTest) ... 
python.exe(35957,0x7fff701d1720) malloc: *** mmap(size=-
9223372036854775808) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
ok
