Building LFS: Segmentation fault with make on a graphical shell

I'm building a LFS system following the steps from the book (version 7.6, though I think the problem is not related to a specific version). After building the toolchain (chapter 5) now I'm into building the system proper (chapter 6).

But here's the thing: when I try to build any package from a graphical shell (in my case LXTerminal from the Lubuntu desktop environment) I can unpack the sources and configure the build with ./configure, but on issuing the 'make' command I get a Segmentation fault. If I issue the same command from a text terminal (e.g. hitting Crtl+F2) it works flawlessly.

In both cases:

This puzzles me, because of course it also fails when connected by SSH, which is what I really want to do.

Can anybody give me a hint of why these two terminals behave differently?

(As a final note, I've tried switching to root user from my non-root user ("login shell") with su - and also login in altogether into the GUI as root)

After some serious googling I could figure it out.

The thing that graphical terminals (the ones that are windows on a graphical shell) and SSH sessions have in common is that they use pseudo-terminals (PTYs) instead of traditional terminals (TTYs). So I focused on the mounting of the virtual filesystem devpts that implements those pseudoterminals. Then I found this answer and tried to bind mount /dev/pts instead of doing a standard mount like the books says:

mount --bind /dev/pts "$CHROOT/dev/pts"

And it worked! Make no longer segfaults.
