Compilation error OTP-27 : asmjit/core/virtmem.cpp:288:3: internal compiler error

[crownedgrouse]

Describe the bug
OTP-27 fail to build with kerl or even manually on 18.04.1-Ubuntu SMP x86_64 GNU/Linux.

A bug #8065 was already reporting this and state that gcc 8 or above might fix this, but installing highest deb package gcc ( 8.4.0 ) available does not work for me.
Can OTP team be more precise how to handle the case ?

To Reproduce
kerl build 27.0.1 27.0.1 on 18.04.1-Ubuntu SMP x86_64 GNU/Linux with gcc-8.4.0

Affected versions
27.0 and 27.0.1

For what it worth, I reach to compile with gcc 9.4.0 (Ubuntu 20.04.2).
A clear statement in Install procedure and/or configure should warn on minimal gcc version to be used.

Thanks for your report! The latest supported version of GCC is 11.x which makes GCC 8.x very old at this point. I think we can't be much clearer than "use a compiler that is actively maintained and file bugs with them if you run into issues." :-/

Interestingly, AsmJit's CI pipeline tests GCC 7+ and it all works:

If there is a trivial fix to this I would not really mind, but it's impossible to verify.
