Compiling with GCC error: cc1 out of memory error

I have a machine running Xubuntu 64 bit and I'm trying to compile my pretty long C code. I am using gcc.

I chrooted in a raspbian stretch environment because the executable code must run on my Raspberry PI 3 model B+. To chroot I followed these instructions:

sudo mount /dev/sdb2 /mntsudo apt-get install qemu qemu-user qemu-user-staticsudo cp /usr/bin/qemu-arm-static /mnt/usr/bin/ sudo chroot /mnt

After get inside the raspbian environment I executed:

gcc -Os $(python3-config --cflags --ldflags) Code.c -o ExecutableCode

and got this output:

cc1: out of memory allocating 32324 bytes after a total of 543821824 bytes

The computational capabilities of my computer are pretty high (my PC is a workstation), therefore I do not believe that memory runs out. Does someone have ideas?
