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):

[...]

valgrind: m_mallocfree.c:305 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo = 1232, hi = 68.
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.

Does that ring a bell?  Is there a chance this problem was fixed in the
meantime?

Thanks in advance,
Ludovic.
