Hello, While investigating luatex crashes in the TeX Live 2020 package of GNU Guix¹, we identified the following heap corruption reported by Valgrind (this is on GNU/Linux, with glibc 2.33): --8<---------------cut here---------------start------------->8--- sh-5.0$ ~ludo/.guix-profile/bin/valgrind --extra-debuginfo-path=/gnu/store/f933bvd6ab6l2lg6xl6k1a6jwvcls0z6-glibc-2.33-debug/lib/debug "luatex" "-interaction=nonstopmode" "-output-directory=build" "&luatex" "amsbsy.dtx" ==28531== Memcheck, a memory error detector ==28531== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==28531== Using Valgrind-3.16.1 and LibVEX; rerun with -h for copyright info ==28531== Command: luatex -interaction=nonstopmode -output-directory=build &luatex amsbsy.dtx ==28531== This is LuaTeX, Version 1.12.0 (TeX Live 2020) restricted system commands enabled. ==28531== Invalid write of size 8 ==28531== at 0x485C691: lua_pushlstring (in /gnu/store/w20xxg8p0wksbrxxvj3y46fngvr3954w-texlive-bin-20200406/lib/libtexlua53.so.5.3.5) ==28531== by 0x568E03: load_hyphenation (in /gnu/store/w20xxg8p0wksbrxxvj3y46fngvr3954w-texlive-bin-20200406/bin/luatex) ==28531== by 0x56B41C: undump_language_data (in /gnu/store/w20xxg8p0wksbrxxvj3y46fngvr3954w-texlive-bin-20200406/bin/luatex) ==28531== by 0x4DFB9F: load_fmt_file (in /gnu/store/w20xxg8p0wksbrxxvj3y46fngvr3954w-texlive-bin-20200406/bin/luatex) ==28531== by 0x4EF0ED: main_body (in /gnu/store/w20xxg8p0wksbrxxvj3y46fngvr3954w-texlive-bin-20200406/bin/luatex) ==28531== by 0x45118D: main (in /gnu/store/w20xxg8p0wksbrxxvj3y46fngvr3954w-texlive-bin-20200406/bin/luatex) ==28531== Address 0xae14170 is 0 bytes after a block of size 1,168 alloc'd ==28531== at 0x483EBE1: realloc (in /gnu/store/jlmh0jbgr6zn4iyvhfbvxps8pykzj5ry-valgrind-3.16.1/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==28531== by 0x46695D: ???

This is probably caused by your program erroneously writing past the end of a heap block and corrupting heap metadata. If you fix any invalid writes reported by Memcheck, this assertion failure will probably go away. Please try that before reporting this as a bug. --8<---------------cut here---------------end--------------->8--- Does that ring a bell? Is there a chance this problem was fixed in the meantime?
