This is what I do and see:

GNU gdb (GDB) 11.1

(gdb) break maybe_defer_native_compilation RET

'Thread 1 hit Breakpoint 1' starts when I try to 'C-x C-f' a .tex file
in Emacs.  And then I can use n, s within the debugger.  But I don't get
any error and such.  Does this make sense to you?  I'm not really
familiar with GDB.

Fine with me.  Currently, I can reproduce it reliably.
