[Pkg-erlang-devel] Bug#1023673: erlang-base: erlang runtime crashes on armel (segmentation fault)

[Igor Rudchenko]

Package: erlang-base
Version: 1:23.2.6+dfsg-1
Severity: important

Dear Maintainer,

After upgrading Debian from 10 to 11 on armel hardware (Qnap TS-410 and
TS-421) I found that erlang runtime no longer works.

First I tried to found the last working debian version from snapshots -
it turned out to be 1:23.0.3+dfsg-1. Erlang runtime started crashing
from 1:23.0.4+dfsg-1 version and looks like all binary builds after this
one is broken on armel.

Debian switched from gcc-9 to gcc-10 for 1:23.0.4+dfsg-1 build.

Attempts to build from source with gcc-10 or gcc-12 failed for all
versions that I tried - 23.0.3, 23.0.4, 25.1.2, but all builds were
successful with gcc-9. Also the builds were successful with newer
versions of GCC and -O1 level of optimization.
