Bug ID: 94953
Summary: A lot of false maybe-uninitialized warnings with O3
Product: gcc
Version: 9.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: olaf.krzikalla at dlr dot de
Target Milestone: ---
See https://godbolt.org/z/nh2gJ9
The warnings only appear with -O3. They only appear for 7<=Blocksize<=16.
They disappear, if you comment out line 32, which is unrelated to
oldDestinationCache.
I'd like to know what is going on here.
