Re-assign to Perl. The crash occurs in the interpreter, automake has nothing to do with it.

@bojov.ac.rs Hi, how to reproduce this issue? 

As I see pdf-tools-install is lisp code (this https://github.com/politza/pdf-tools one?). 
Is it installed from the package or how?

Could you describe the process?

Fedora 40, KDE Plasma 6, emacs from the Fedora repos, doom-emacs, pdf module enabled in the user's init.el file (after enabling the /path/to/doom sinc module).
Since the pdf-tools package (http://github.com/vedang/pdf-tools/ also in the elpa.nongn repo) requires (re)building the epdfifno program then I have to call the M-k pdf-tools-install command.
During command execution, it starts building the epdfinfo program and calls automake.

Epdfinfo is built and working as expected.
Another note, F40 is installed with English language support, and I added Serbian and Serbian Latin keyboards and the glibc-langpack-sr package. I also copied the locale.conf (from the Gnome installation) with the following content :
LANG="en_US.UTF-8"
LC_NUMERIC="sr_RS.UTF-8@latin"
LC_TIME="sr_RS.UTF-8@latin"
LC_MONETARY="sr_RS.UTF-8@latin"
LC_PAPER="sr_RS.UTF-8@latin"
LC_MEASUREMENT="sr_RS.UTF-8@latin"

I suspect this may be a problem due to a bug in the freelocale function?

@bojov.ac.rs If you think that the problem could be with locales, you could change to en_US and test.
We need to simplify the case.

I tried in the following configurations:
Fedora 40 workstation - from locale.conf:
- LANG="en_US.UTF-8" only.
- custom locale.conf
LANG="en_US.UTF-8"
LC_NUMERIC="sr_RS.UTF-8@latin"
LC_TIME="sr_RS.UTF-8@latin"
LC_MONETARI="sr_RS.UTF-8@latin"
LC_PAPER="sr_RS.UTF-8@latin"
LC_MEASUREMENT="sr_RS.UTF-8@latin"

Fedora 40 KDE Plasma 6 - with locale.conf:
- LANG="en_US.UTF-8" only.

autoreconf (called from pdf-tools-install) works as expected - no sigsev 11

It not works in KDE Plasma 6 with a custom locale.conf.

Note: locale.conf is customized with "Region & Language" from System Settings in both environments.
I also noticed that the Gnome environment settings are applied system-wide, while in KDE the same settings are applied per user.

Reproducer without emacs on Fedora 40:

 sudo localectl set-locale LANG="en_US.UTF-8" LC_NUMERIC="sr_RS.UTF-8@latin" LC_TIME="sr_RS.UTF-8@latin" LC_MONETARY="sr_RS.UTF-8@latin" LC_PAPER="sr_RS.UTF-8@latin" LC_MEASUREMENT="sr_RS.UTF-8@latin"
 git clone https://github.com/vedang/pdf-tools.git
 cd pdf-tools/server
 automake --add-missing --copy --force-missing

Result:

 Segmentation fault (core dumped)

@bojov.ac.rs I added the link to the Perl issue, which is known. The root cause is »LC_ALL=«.

The simple reproducer is (from Perl issue):

 $ cat crash.pl
 #!/usr/bin/perl

 require threads;
 require Thread::Queue;

 $ export LC_ALL=
 $ perl crash.pl && echo OK
 Segmentation fault (core dumped)
 $ export LC_ALL=en_US.UTF-8
 $ perl crash.pl && echo OK
 OK

Hm,
 export LC_ALL= 
isn't enough. 

 sudo localectl set-locale LANG="en_US.UTF-8" LC_NUMERIC="sr_RS.UTF-8@latin" LC_TIME="sr_RS.UTF-8@latin" LC_MONETARY="sr_RS.UTF-8@latin" LC_PAPER="sr_RS.UTF-8@latin" LC_MEASUREMENT="sr_RS.UTF-8@latin"
is enough.

I tested this issue in Fedora 40 and Fedora Rawhide in mock. In f40 is present, in rawhide is not present.
