pandoc segfaults when run as a plain user but not as root

pandoc segfaults when run as a plain user but not as root

[Martin Brooks]

[-- Attachment #1.1: Type: text/plain, Size: 1739 bytes --]

Hello

I've just installed pandoc from the .deb file distributed from the primary 
site 
(i.e. https://github.com/jgm/pandoc/releases/download/2.9.2.1/pandoc-2.9.2.1-1-amd64.deb 
)

The installed binary segfaults when run as an ordinary user, but not when 
run as root:

$ /usr/bin/pandoc --version
Segmentation fault

$ sudo /usr/bin/pandoc --version
pandoc 2.9.2.1
Compiled with pandoc-types 1.20, texmath 0.12.0.1, skylighting 0.8.3.2
Default user data directory: /root/.local/share/pandoc or /root/.pandoc

The underlying operating system is a freshly installed Debian 10:


$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 10 (buster)
Release:        10
Codename:       buster


The problem happens consistently even after a reboot.  An strace isn't 
especially enlightening:

$ strace /usr/bin/pandoc --version
execve("/usr/bin/pandoc", ["/usr/bin/pandoc", "--version"], 0x7fff76901a28 
/* 20 vars */) = -1 EPERM (Operation not permitted)
+++ killed by SIGSEGV +++
Segmentation fault


Any ideas what the problem might be?

Regards

Martin A. Brooks

That's odd, I haven't heard any reports like this.
Can anyone else reproduce this?

Btw I can't reproduce on my debian stable system.
What kind of system are you running on?

It's an openstack-based virtual machine. 4 cores, 4 gigs of RAM.

I don't have any advice to offer; I haven't seen this before.
You can always compile from source on that system.
