[New-bugs-announce] [issue5614] Malloc errors in test_io

New submission from Ronald Oussoren <ronaldoussoren at mac.com>:

The malloc warnings happen on OSX, with a fresh checkout of the python3 
branch. Python was build using --enable-universalsdk=/ --with-universal-
archs=all, on a x86_64 capable laptop running Leopard.

The issue goes away when running from the commandline, the "-E -bb" 
flags that 'make test' use seem to be involved in the issue.


test_io

Testing large file ops skipped on darwin.
It requires 2147483648 bytes and a long time.
Use 'regrtest.py -u largefile test_io' to run it.
