Hey all,
The travis tests for a library I work on just stopped working, and I
tracked down the bug to the following test case. The file
"MDTraj/testing/reference/mdcrd.nc" is a netcdf3 file in our repository (
https://github.com/rmcgibbo/mdtraj/tree/master/MDTraj/testing/reference).
this script:
conda install --yes scipy==0.13 numpy==1.7 --quiet
python -c 'import scipy.io; print
scipy.io.netcdf.netcdf_file("MDTraj/testing/reference/mdcrd.nc").variables["coordinates"][:].sum()'
conda install --yes scipy==0.14 numpy==1.8 --quiet
python -c 'import scipy.io; print
scipy.io.netcdf.netcdf_file("MDTraj/testing/reference/mdcrd.nc").variables["coordinates"][:].sum()'
works on scipy==0.13 numpy==1.7, but segfaults on scipy==0.14 numpy==1.8. I
got the segfault on both linux and osx.
I tried compiling a new version of numpy from source with debug symbols
using `python setup.py build_ext -g install`, but couldn't get a useful
traceback.
$ gdb --core=core
(gdb) bt
#0 0x00007fd4f7887b18 in ?? ()
#1 0x00007fd4f786ecc6 in ?? ()
#2 0x0000000000000000 in ?? ()
Anyone have any advice for tracking this down?
-Robert
