Hi Michael,
thanks for the report. I initially could not reproduce as this seems not
to happen when generating Python bindings.
Here is a Dockerfile to check if this is fixed:
-----------------------------------------------------
FROM debian:sid
MAINTAINER Torsten Landschoff <tors...@debian.org>
RUN adduser maint --disabled-password --gecos "SWIG maintenance"
RUN apt-get update
RUN apt-get -yy install swig3.0
ADD
https://raw.githubusercontent.com/swig/swig/8bc38dc0070740d1a4b1ec522f80c7e292a74850/Examples/test-suite/nested_scope.i
/home/maint/
RUN chown maint:maint /home/maint/*
USER maint
WORKDIR /home/maint
# For some reason this works fine
RUN swig3.0 -c++ -python nested_scope.i
# But using Tcl or Ruby as target language leads to the crash
RUN swig3.0 -version
RUN swig3.0 -c++ -ruby nested_scope.i
RUN swig3.0 -c++ -tcl nested_scope.i
ENTRYPOINT ["/bin/bash", "-i"]
-----------------------------------------------------
Running this through "docker build", I get the following output:
torsten@horatio:~/debwork/swig-768280$ sudo docker build .

Step 11 : RUN swig3.0 -c++ -ruby nested_scope.i
---> Running in 9d98770ffe45
Segmentation fault (core dumped)
INFO[0004] The command [/bin/sh -c swig3.0 -c++ -ruby nested_scope.i]
returned a non-zero code: 139
So I can confirm this happens when generating Ruby or Tcl bindings. I
did not check others apart from Python (which does not crash).
So far about that, now I have to get access to Subversion again. I moved
my ssh key to a hardware token and currently my setup refuses to use it
for SSH login.
Greetings, Torsten
