Hi,
I have generated python binding with pyplusplus, I was building it all
the time with bjam using debug build type. Everythin worked fine.
Now when I tried to build it in release mode, importing the module fails
with "Segmentation fault" message.
$ PYTHONPATH="./bin/gcc-4.1.2/release" python26
Python 2.6.5 (r265:79063, Apr 9 2010, 11:16:46)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Cream
Segmentation fault
I'm using:
- gcc 4.1.2
- boost 1.44
- python 2.6.5
- gccxml 0.9( 1.135 )
- pygccxml and pyplusplus from SVN
The difference betweend debug and relase shows during compilation.
There's an additional warning message when compiling in release:
