Makefile balloons to huge size with seemingly infinite repetition on some Linux systems

[ilmari-lauhakangas]

We use curl in LibreOffice development. Recently, a new contributor building LibreOffice on Debian 11 noticed that curl's Makefile in LibreOffice's workdir took 1.5 terabytes of space. This was observed with curl 7.85.0 and persists with 7.86.0.

While I don't see this infinite ballooning myself, my Makefile does get unusually large, 13.2 MiB. I am pasting below the result of printing duplicate lines with counts. This is on Arch Linux.

$ sort workdir/UnpackedTarball/curl/lib/Makefile | uniq -cd

I've seen this happen as well but I've not figured out why or what causes it...

[dfandrich]

It's automake that generates the file, so it's probably an issue with it.

[jay]

Though this may not be a curl bug it would still be nice to know what causes it if you are able to bisect it.

[ilmari-lauhakangas]

I cloned curl repository and I can't repro the size problem after running configure with the options that LibreOffice uses. Makefile size is 68 KiB.

@ilmari-lauhakangas using which automake version?

[ilmari-lauhakangas]

@ilmari-lauhakangas using which automake version?

automake is 1.16.5

[bagder]

The 7.86.0 tarballs were made with 1.16.5 too, more specifically the 1.16.5-1.3 package in debian (unstable).

[ilmari-lauhakangas]

I cloned curl repository and I can't repro the size problem after running configure with the options that LibreOffice uses. Makefile size is 68 KiB.

Sorry, this is not true: I was looking at the wrong Makefile! lib/Makefile does grow to 13.2 MiB.

[bagder]

The 628 number is curious. It seems to be the number of lib source files times two!

$ cd [curl-src]/lib
$ find . -name "*.[ch]" | wc -l
314

[ilmari-lauhakangas]

I tried running autoreconf and configure for a bunch of older tags, down to 7.32.0 or 70812c2. The size of the Makefile kept getting smaller, but is still 6.6 MiB at 7.32.0, with the repetition number being 448.

[bagder]

Right, because this is probably because of automake. If you would downgrade that, you could potentially figure out which version that introduced this behavior.

[ilmari-lauhakangas]

I have a local automake build set up now per https://git.savannah.gnu.org/cgit/automake.git/tree/HACKING

Curl doesn't seem to have any env var for aclocal, though, so if I do

am=/home/user/automake
env PERL5LIB=$am/lib AUTOMAKE="$am/bin/automake" ACLOCAL="$am/bin/aclocal" autoreconf -fi

I get

aclocal: error: couldn't open directory '/tmp/amdev/share/aclocal-1.16': No such file or directory

Any ideas?

[bagder]

A broken aclocal install?

[ilmari-lauhakangas]

A broken aclocal install?

No, I mean I want to point to the built aclocal in automake/bin. Should I hardcode the path in curl source or what do you propose?
