I installed a Pop!_OS VM and tracked down the issue. This is a Boron bug which I have just pushed a fix for. The Makefile was also broken on Pop! and a shared library (the default) got installed into the wrong directory. Thanks for your report.
I have also asked @SiegeLord to update the PPA for Ubuntu 21.10.

Github has the latest code. Did you use any configure options? What compiler
is being used?
See if "./src/xu4 -h" runs without crashing. Does the Boron interpreter you
built run? Does the Linux snapshot from http://xu4.sourceforge.net/
download.php run on your system?

The compiler is gcc version 11.2.0 (Ubuntu 11.2.0-7ubuntu2)
No configure options.
The binary from .net does not crash with the same error, but complains:
u4: error: Unable to initialize Allegro

Please let me know what happens when "./src/xu4 -h" is run.
What version of Allegro are you using? On Ubuntu the liballegro-acodec5.2
package is also needed. The README in the snapshot archive has instructions
for installing Allegro on Ubuntu.

$xu4 -h provides normal output (from both my repo build and the downloaded version), but the other options still core:

xu4 -v finds/opens it's dependencies before crashing, fwiw.
Thanks for walking me through this.

What is the -v output? The latest Allegro is version 5.2.7.

I'll try building Allegro 5.2.7 from source, the base repo doesn't have that build yet, and the PPA from Allegro doesn't have impish builds.
The -v output is:

Are you able to run gdb? I'd try that before building Allegro.

If you can't debug the program here's a patch to narrow down the point of failure. Based upon the verbose log, configInit() is probably failing.

I have made some progress (of a sort). Muddling my way around gdb (in over my head, in case it wasn't obvious) it looked like init was stepping through some libboron "stuff". I had also seen in the makefiles that some of that was avoided if I used the ./configure --xml flag, so I gave that a shot against a clean clone from github. There was a build failure with line 5 of src/xu4.h looking for a "notify.h" file that appeared to be in the support directory, so I changed it to #include "support/notify.h" and the build succeeded. The resulting build succeeded and runs, but crashes out after character generation with an xml validation error several pages of (probably expected?) "No declaration for " messages :
$ ./src/xu4
xu4: warning: xml validation error:
No declaration for element armors
No declaration for element armor
...<SNIP>...

That seems to be a detour from the original issue, but thought it might help narrow things down at least to know that cutting out boron changes things significantly. Happy to provide more specific gdb output (or the core file) if that's helpful.

Thanks for your guidance and for tracking the bug down. I look forward to some classic Ultima nostalgia!
