<pre>I can confirm this issue. Using tinydrm display with
weston 4.0.90
linux 4.17.2
KMS-DEBUG: unmapped buffer 2 (was 0x69eaa000)
KMS-DEBUG: unmapped buffer 2 (was (nil))
KMS-DEBUG: destroyed buffer 2
The process shows really weird behavior after this, like missing memory
regions.
<span class="quote">>* adding condition on above munmap() to call it only if ro_mapped is not NULL</span >
This was the solution I went with too, but added it for both pointers ;)</pre>
