[linux-lvm] [lvm2cmd] Heap destruction by lvm2_exit()?

[Alasdair G Kergon]

Your test program works for me:

$ valgrind ./a.out
==14092== Memcheck, a memory error detector
==14092== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al.
==14092== Using Valgrind-3.5.0 and LibVEX; rerun with -h for copyright info
==14092== Command: ./a.out
==14092== 
Some text to output
Variable before: "Other text"
Variable after: "Other text"
==14092== 
==14092== HEAP SUMMARY:

==14092==   total heap usage: 161 allocs, 161 frees, 10,620,400 bytes allocated
==14092== 
==14092== All heap blocks were freed -- no leaks are possible

What version of lvm2 are you using?
Retest with upstream source?
What lvm configure options are you using?
