[Pkg-opencl-devel] Bug#909379: Info received (Bug#909379: segfault when leaving the python3-dbg interpreter)

[PICCA Frederic-Emmanuel]

Here a backtrace,

So the segfault comes from the cffi backend.
Since cffi is used during the pyopencl build,maybe something changed
between the cffit versionduring the build and the current one.

pyopencl was build with python-cffi all 1.11.5-1

and used with the cffi-backend 1.11.5-3.

somaybe there is a ABI incompatibility between these versions.
