"This only happens on one host (running Debian stable as the others
do), which is quite low on memory".

How low on memory? [Everything is in swap? etc]
What kind of shell do you use?
Are the environment variables identical between systems that work
non-interactively and the one that doesnt?
What is the stable kernel you are running? And stable glibc?
Does the kernel report anything when this occurs.

I don't have any Debian stable systems to compare with.
