Looks like you are right.

I managed to reproduce this locally, and I get this:

  [15746515.856452] Out of memory: Kill process 2148 (sed) score 553 or sacrifice child
  [15746515.857476] Killed process 2148 (sed) total-vm:1180204kB, anon-rss:1167084kB, file-rss:0kB

FWIW, the sed script is 2.6M and 13692 lines, and DEBIAN/md5sums is 3.2M and
29035 lines.

However I do not understand what ‘parallel level’ you are talking about.
If it is the package build parallel level, then it is unrelated — what gets
killed is a single sed command (“sed -i -f $sedscript DEBIAN/md5sums”).

The only workaround I can apply is disabling the PNGs compression by 
exporting NO_PNG_PKG_MANGLE=1.
