ERROR Parsing MAPI block

[AndyM48]

libytnef 1:2.1.2
artix 6.9.7

The error is similar to several others, but I do not know why it occurs and how to fix it:

Run ytnef -f . winmail.dat
Ran ytnef with error 0 and result "ERROR: invalid alloc size 114 at ytnef.c : 469, suspected corruption (exceeded 100 bytes)
ERROR Parsing MAPI block"

Also I wonder why the error returned is 0?

$ tnef winmail.dat works fine.
