null check is not enough, see the below quoted log:
--- snip ---
0029:Call imm32.ImmGetIMCCSize(bf9c73e5) ret=0d6d3545
--- snip ---

Another example:
--- snip ---
0029:Call imm32.ImmGetIMCCSize(00000190) ret=0a193545
--- snip ---

Could you provide more details for how to check the validity of the
handle in the right way?

Thanks a lot!
