[issue7144] imp.load_module in thread causes core dump on OSX 10.6

Adam Doherty <dohertywa[at]gmail.com> added the comment:

Hello:

Having the same issues in a web app I've written. Tested with the
default 2.5 and 2.6 on Snow Leopard and 2.5 on Ubuntu 8.04 (no problems
under Linux) Replaced the default Python with 2.6.4 from python.org, my
app no longer crashes.

Hope it helps.

[issue7144] imp.load_module in thread causes core dump on OSX 10.6 [In reply to]

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

The crash is caused by loading any extension that happens to link with
CoreFoundation on a secondary thread, unless CoreFoundation was already
initialized.

The CF framework contains a constructor that explicitly aborts when it
is not called on the main thread (all of this on Snow Leopard only).

I've found a workaround for this issue: ensure that Python is linked to
the CoreFoundation framework, that way CF will be initialized when
Python starts.

I'm working on a clean patch for this
