 Unfortunately I can not reproduce. My processor is an Intel K variant
CPU, six cores and twelve threads, 64 Gb of RAM.
GM is 1.3.40 with two security fixes backported, compiled with GCC
v12.2.0. Tried with three PNG images, all memory consumption is static
from the beginning. Do I need some special case of PNG files to
experience this issue?

 Do you think it might be a problem with another system component, a
GCC optimization or this is fixed meanwhile? At least I do wonder why
this issue is CPU / machine dependent.
