[New-bugs-announce] [issue23340] armv7l C++ exceptions issue

[Alex Potapenko]

New submission from Alex Potapenko:

I run Python on an arm-brcm-linux-uclibcgnueabi router. Python was cross-compiled using hndtools-arm-linux-2.6.36-uclibc-4.5.3 toolchain. While trying to use deluge, I realised that there's something wrong with handling C++ exceptions in C++ extension modules: they're not being caught at all. I tested whether C++ exception handling works on my system in general, and concluded it does work fine. I then wrote a simple C++ extension module with a try-catch block in the init function, that has a "throw 1" in the try section and a "catch (...)" section (see module.cpp), and I got "terminate called after throwing an instance of 'int'" when trying to load the module. Tested this with Python 2.7.9 and 3.4.2, however I had similar issues with other versions, such as 2.7.3 and 2.6.9.

I'm not sure whether this is a Python issue, or a specific build issue, but I'm stuck here and any help is greatly appreciated!
