It depends on the Ubuntu release. My Ubuntu 18.04 machine is running gcc (Ubuntu 
7.3.0-16ubuntu3). I don't observe the symptoms you're seeing, when I build on 
the emacs-26 branch and use './configure --with-modules'.

Doesn't sound likely. The assembly code you sent looks fishy, though. You might 
try running gcc -S and/r gcc -E on the affected module, with the same 
compile-time flags that 'make' is using; use 'make V=1' to see them.
