GCC compilation within docker with "-j" - docker

Question

I got strange errors while compiling my project within the docker container when I am using -j option of make.
The errors look like this:
/root/projects/obj/linux_debug/src/myos_make/libmyos.a: error adding symbols: Cannot allocate memory
/usr/protobuf-3.9.2/lib/libprotobuf.a: error adding symbols: Bad address
Compiling the same project inside the container without -j and outside the container with -j passes ok.
The Dockerfile :
#
# This docker must be built from projects/src folder as context
#
FROM ubuntu:18.04 as base
# copy the dockerfile to make it possible to keep track of the cntent of the image
COPY ./docker_build/docker_files/Dockerfile.ubuntu18.04-builder $HOME/.
