PARSER VERSION NUMBER: 7.1.0

PLATFORM (SPARC, HP700, PC, etc.): PC

OS AND VERSION: Microsoft Windows 11 Enterprise 22H2, Build 22621.3296

REPORTED BY: Michael Mirmak, Intel Corporation

DATE: March 28, 2024

TITLE: Memory leaks caused by algmod.c, ami.c and cmn.c

DESCRIPTION OF BUG:

Executing the following command on the enclosed .ami file results in *no* errors or warnings under
ibischk7_64, 7.2.1:

	ibischk7_64.exe -ami leak-97a9f20e3ff2ac03cc313c342de4e42d556d0aca.ami

However, according to the clang compiler and AddressSanitizer, this .ami file will cause about
20 KB of memory leakage due to routines in the source code files algmod.c, ami.c, and cmn.c from ibischk7 7.1.0.

For any given single run or simulation, this is trivial.  But for larger runs (e.g., a statistical analysis),
this could mean a significant amount of lost memory.
