Hello,


The generated aux file indeed looks strange:
ametzler at argenau:/tmp/GNUTLS28$ cat -n ./gnutls28/b4deb/doc/gnutls.t2p/gnutls.t2d/pdf/build/gnutls.aux | head -n 108  | tail -n5
   104  @xrdef{SRTP-snt}{Section at tie 3.6.7}
   105  @xrdef{gnutls at unhbox @voidb at x @kern .07em @vbox {@hrule width.3em height.1ex}@kern .07em srtp at unhbox @voidb at x @kern .07em @vbox {@hrule width.3em height.1ex}@kern .07em profile at unhbox @voidb at x @kern .07em @vbox {@hrule width.3em height.1ex}@kern .07em t-title}{!!float!!=Figure}
   106  @xrdef{gnutls at unhbox @voidb at x @kern .07em @vbox {@hrule width.3em height.1ex}@kern .07em srtp at unhbox @voidb at x @kern .07em @vbox {@hrule width.3em height.1ex}@kern .07em profile at unhbox @voidb at x @kern .07em @vbox {@hrule width.3em height.1ex}@kern .07em t-snt}{Figure at tie 3.2}
   107  @xrdef{gnutls_srtp_profile_t-lof}{Figure at tie 3.2: @xeatspaces{Supported SRTP profiles}}
   108  @xrdef{SRTP-pg}{15}


But I am quite at loss here, the same source built successfully in the past,
so this looks like TeX breakage. The successful build used:
texinfo 7.1.1-1
texinfo-lib 7.1.1-1+b1
texlive-base 2024.20250309-1
texlive-binaries 2024.20240313.70630+ds-6
texlive-latex-base 2024.20250309-1
texlive-plain-generic 2024.20250309-2

Any help appreciated.
