[Pixman] Sanitizer undefined

Sun Nov 18 07:08:54 UTC 2018

Hi,

I just run the stress-test with CFLAGS="-fsanitize=undefined"

I have lots of
"runtime error: signed integer overflow: 2147254245 + 589815 cannot be
represented in type 'int'"
runtime error: left shift of 1 by 31 places cannot be represented in type
'int'
runtime error: left shift of negative value -26

Do you think these errors should be solved ?

You can find enclosed the report,
