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'. > i guess it's always possible the optimizer is doing the right thing > because of some programming error, maybe a mis-placed "const" on an > extern, something like that. 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.
