Dirty but working ok for development, we should add some way to pass the option directly (for example when SAGE_DEBUG is yes or letting the user pass falgs to put into EXTRAFLAGS). By the way, from http://docs.python.org/devguide/setup.html#compiling-for-debugging : You should always develop under a pydebug build of CPython (the only instance of when you shouldn’t is if you are taking performance measurements). Even when working only on pure Python code the pydebug build provides several useful checks that one should not skip.
:) I then had to rebuild Cython (and to rebuild the Sage library), and gdb does not seem to work anymore. And when I say it fails quite everywhere when using the debug build, hoping that I did not break everything myself with the debug build, in fact it mostly fails before doctesting anything, but I still see pointers to category objects in the trace I get (without gdb unfortunately): python: Modules/gcmodule.c:326: visit_decref: Assertion `gc->gc.gc_refs != 0' failed.
