I could not repro this bug with any autoconf version currently available in the portage tree. That is: - autoconf-2.13-r8 - autoconf-2.69-r9 - autoconf-2.71-r6 - autoconf-2.71-r7 - autoconf-2.72-r1 I do have =sys-devel/gcc-14.2.1_p20240921::gentoo as the default compiler. Maybe that's the difference...

reproducible with autoconf-2.72-r1
(In reply to Arniii from comment #6) > reproducible with autoconf-2.72-r1 The issue is well-understood and depends on bug 926120. No need for further confirmations.
