Pulled from JE repo commit 756ed48 2026-04-09 16:21:08,
built with commands:

Note: without USE_EMU_AVX=0 there are a lot of errors:

It is no need to set _ASSERT=1 _ASSERT2=1 unless you have a specific reason, otherwise it prints lots of error code:....
gcc-13 in github action has no problem to compile with USE_EMU_AVX=1,
perhaps gcc-15 has changed its behaviour. A possible workaround is to replace those inline functions with macros, but that will
require a lot of effort. BTW clang has no problem with it.
USE_EMU_AVX=0 is not working and I think had never worked before.
I have made some progress but it still crashed when freeing a large block of memory.
A simple test is
$ <@": <i.4294967296 2147483648 0
running it twice with crash J.

[bilam]

I have fixed the last bug in USE_EMU_AVX=0
I will upload to JE repos later.

Trying to switch to gcc-13:

cd make2
./clean.sh
LANG=C CC=gcc-13 jplatform=linux j64x=j64 _DEBUG=2 USE_EMU_AVX=1 ./build_libj.sh

failed with the same errors. I guess I should remove gcc-15 completely, but I didn't. I've tried clang instead and was succeeded. Now the crash # 1 is gone, but # 2 still persist:

I checked. Your script also crashed for j64 EMU_AVX2=0 and J32 linux.
It failed on all platforms and is a JE bug. Since it is emulation unrelated, I will leave others to investigate.
