Hi all,
So I tried what was advised to me.
python -c 'import pylab; pylab.plot([4]);'
terminate called after throwing an instance of 'std::exception'
terminate called recursively
Abort
which happens here:
14 agg::trans_affine
15 py_to_agg_transformation_matrix(PyObject* obj, bool errors = true)
16 {
17 PyArrayObject* matrix = NULL;
18
19 try
20 {
21 if (obj == Py_None)
22 throw std::exception();
Since I compiled w/o optimization flags I have this now:
#11 0xfffffd7ff46cf0b6 in __cxxabiv1::__cxa_throw (obj=<value
optimized out>, tinfo=<value optimized out>,
dest=<value optimized out>) at
../../../../../libstdc++-v3/libsupc++/eh_throw.cc:83
#12 0xfffffd7ff4a3c708 in py_to_agg_transformation_matrix
(obj=0x774380, errors=false) at src/agg_py_transforms.cpp:22
#13 0xfffffd7ff4a4132e in _path_module::update_path_extents
(this=0x144e230, args=...) at src/path.cpp:380
#14 0xfffffd7ff4a537ce in
Py::ExtensionModule<_path_module>::invoke_method_varargs
(this=0x144e230, method_def=0x14009b0,
args=...) at ./CXX/Python2/ExtensionModule.hxx:184
#15 0xfffffd7ff4a389df in Py::method_varargs_call_handler
(_self_and_name_tuple=0x1244170, _args=0x1977fb0)
at CXX/Python2/cxx_extensions.cxx:1714
#16 0x00000000004a6071 in call_function (f=0x201e980, throwflag=<value
optimized out>)
at /usr/local/src/lang/Python-2.7.1/Python/ceval.c:4012
#17 PyEval_EvalFrameEx (f=0x201e980, throwflag=<value optimized out>)
at /usr/local/src/lang/Python-2.7.1/Python/ceval.c:2665
#18 0x00000000004a79c1 in PyEval_EvalCodeEx (co=0x123a130,
globals=<value optimized out>, locals=<value optimized out>,
args=0x201eb20, argcount=<value optimized out>, kws=0x3,
kwcount=2, defs=0x12467e8, defcount=3, closure=0x0)
at /usr/local/src/lang/Python-2.7.1/Python/ceval.c:3252
The function has now obj=0x774380 as an argument instead of <value
optimized out>
So what is generating a PyNull object is in src/path.cpp:380
but this file doesn't exist! If I look in _path.cpp though this is
where it fails:
360 ::get_path_extents(path, trans, &extents_data[0],
&extents_data[1],
361 &extents_data[2], &extents_data[3],
&xm, &ym);
I have no idea how to debug this since it seems the problem are in the
CXX extensions (calls to ceval.c)
Any idea how I can narrow down the problem?
Thanks!
