Hello Jeff lib/malloc/malloc.c, if you want to view it online: https://git.savannah.gnu.org/cgit/bash.git/tree/lib/malloc/malloc.c Maybe libasan is providing its own malloc and there is a conflict of calls between theirs and bash mallocs. I would recommend to rebuild bash with the parameter --without-bash-malloc and see if that makes the error go away (which is likely). Best regards, and apologies for the previous empty reply.
