Re: [Matplotlib-users] Help in solving a segfault problem?
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 0xfd7ff46cf0b6 in __cxxabiv1::__cxa_throw (obj=, tinfo=,
dest=) at
../../../../../libstdc++-v3/libsupc++/eh_throw.cc:83
#12 0xfd7ff4a3c708 in py_to_agg_transformation_matrix
(obj=0x774380, errors=false) at src/agg_py_transforms.cpp:22
#13 0xfd7ff4a4132e in _path_module::update_path_extents
(this=0x144e230, args=...) at src/path.cpp:380
#14 0xfd7ff4a537ce in

args=...) at ./CXX/Python2/ExtensionModule.hxx:184
#15 0xfd7ff4a389df in Py::method_varargs_call_handler

#16 0x004a6071 in call_function (f=0x201e980, throwflag=)
at /usr/local/src/lang/Python-2.7.1/Python/ceval.c:4012
#17 PyEval_EvalFrameEx (f=0x201e980, throwflag=)
at /usr/local/src/lang/Python-2.7.1/Python/ceval.c:2665
#18 0x004a79c1 in PyEval_EvalCodeEx (co=0x123a130,
globals=, locals=,
args=0x201eb20, argcount=, 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
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!

Thanks much for the reply! I'll try your advice as soon as I can. BTW, I don't think this is a Solaris-related problem. If you look at the pointers in my original post, the same error can happen on other arch (I confess it can be for other reasons though). -n On Sun, Mar 13, 2011 at 1:03 PM, Jouni K.

Re: [Matplotlib-users] Help in solving a segfault problem?
Hi, I didn't get much reply on this issue, so I'm just trying to resurrect the question. If there's no easy answer, could someone help me by giving me a pointer, a method to resolve the problem, or any other quick advice...? Thanks much!

[Matplotlib-users] Help in solving a segfault problem?
Hi all, I am stuck on matplotlib generating a segfault when invoking 'plot'. I've ben trying to solve this problem for a while now but no luck. I've seen many duplicates of this problem on the web, some with solutions, some without. The solution must be something more generic that I'm missing. Here are some of these pointers to the same problem that I have (the backtrace, that I pasted further below, has the same properties) http://old.nabble.com/101-Point-Segmentation-Fault-td27552745.html http://old.nabble.com/weird-error-with-gcc-4.4,-gomp,-cython,-and-matplotlib-td27351399.html http://bugs.gentoo.org/show_bug.cgi?id=338513 So here's my specific setup and backtrace. I hope I can find some help! I'm using the 'agg' backend that's it, and the build and install dir were cleaned up.
