Hello,
Since a while, the docker images from "master" segfault:
```
address@hidden:~$ docker run -it --rm silex/emacs:master
Fatal error 11: Segmentation fault
Backtrace:
emacs(+0x132cae)[0x555966f19cae]
emacs(+0x11925a)[0x555966f0025a]
emacs(+0x13107e)[0x555966f1807e]
emacs(+0x131328)[0x555966f18328]
emacs(+0x1313ac)[0x555966f183ac]
/lib/x86_64-linux-gnu/libpthread.so.0(+0x12890)[0x7f3010977890]
```
The binary is semi-working tho, like for example:
```
address@hidden:~$ docker run -it --rm silex/emacs:master emacs --version

Here attached you'll find the gdb trace and a strace log. I tried to build the image with debug flags using what's in DEBUG, but the errors are similar.
I know that recently the portable dumper branch was merged, I suspect it has to do with the segfault... If necessary, I can bisect to find the offending commit, but I was hoping someone would quickly know what is happening.
This happens even if I run the container in privileged mode.
Kind regards,
Philippe
