libvmmalloc1-debug 1.7-1ubuntu1 (amd64 binary) in ubuntu focal

 The libvmmalloc library transparently converts all the dynamic memory
 allocations into volatile persistent memory allocations. This allows the
 use of persistent memory as volatile memory without modifying the target
 application.
 .
 This package contains a special build of this library meant for debugging
 purposes. It contains extra logging, assertions and expensive checks that
 should not be used otherwise.
