[ipmiutil-developers] Win64: heap leak crashing ipmiutil 3.13

[Rob S. <rob...@nu...>]

Hello All,

Recently I encountered ipmiutil winx64 crashes on Windows Server 2019. I am yet to figure out what the trigger is, but after enabling application verifier I got the following stack:

0:000> !heap -p -a 0xd02fec0
