Hi,
I've compiled
Python 2.7 (r27:82500, Nov 2 2010, 09:00:37)
[GCC 4.4.3] on linux2
with the following configure options
../configure --prefix=/home/john/local/python-dbg --with-pydebug
I've installed numpy and some other packages but when I try to run my
extension code under gdb I get the errors below. Does anyone have any
ideas of how to track down what's happening here? I imagine I've
misconfigured something somewhere. Is valgrind the answer?
Thanks,
John.

I've compiled
Python 2.7 (r27:82500, Nov 2 2010, 09:00:37)
[GCC 4.4.3] on linux2
with the following configure options
../configure --prefix=/home/john/local/python-dbg --with-pydebug
I've installed numpy and some other packages but when I try to run my
extension code under gdb I get the errors below. Does anyone have any
ideas of how to track down what's happening here? I imagine I've
misconfigured something somewhere. Is valgrind the answer?
Thanks,
John.
