[Bug 2065775] [NEW] buffer overflow during debootstrap --variant=fakechroot

[Ken Sharp]

Public bug reported:

Running a debootstrap fakechroot fails during mawk set up.

$ fakechroot fakeroot debootstrap --variant=fakechroot noble noble

Setting up mawk (1.3.4.20240123-1build1) ...
*** buffer overflow detected ***: terminated
Aborted (core dumped)
dpkg: error processing package mawk (--configure):
 installed mawk package post-installation script subprocess returned error exit status 134

Same with Oracular.

A normal debootstrap (no variant) completes without error.

Could be a fakeroot fault. I will reassign if I figure out the cause.
