I’ve just updated an escript based application of mine from Elixir 1.17 to 1.19.

At the same time I attempted to update from OTP 27.2.2 to 28.1.1

After switching to 1.19.3-otp28, nuking the _build folder, and recompiling, the escript binary gives the following error:

=ERROR REPORT==== 20-Nov-2025::14:32:27.189484 ===
beam/beam_load.c(150): Error loading module rez_escript:
  corrupt atom table


escript: exception error: undefined function rez_escript:main/1
  in function  escript:run/2 (escript.erl, line 904)
  in call from escript:start/1 (escript.erl, line 418)
  in call from init:start_it/1
  in call from init:start_em/1
  in call from init:do_boot/3

Going back to 1.19.3-otp27 with 27.3.4.6 and the escript binary works fine.

I couldn’t find anything much sensible via Google and errors in beam_load.c is a bit above my pay grade so I thought I would report it here.
