libmaloc1 1.5-1 (ppc64el binary) in ubuntu jammy

 MALOC is a small, portable, abstract C environment library for object-
 oriented C programming. MALOC is used as the foundation layer for a
 number of scientific applications, including MC, SG, and APBS. MALOC
 can be used as a small stand-alone abstraction environment for writing
 portable C programs which need access to resources which are typically
 architecture-dependent, such as INET sockets, timing routines, and so
 on. MALOC provides abstract datatypes, memory management routines,
 timing routines, machine epsilon, access to UNIX and INET sockets, MPI,
 etc. All things that can vary from one architecture to another are
 abstracted out of an application code and placed in MALOC.
