Summary: [9 regression] wrong code
Product: gcc

Severity: normal
Priority: P3

test program
Hi,
The attached program aborts with gcc 9.x -O{1,2,3} (including recent version of
the Debian package which has picked recent fixes to the gcc 9 branch). Adding
-fno-strict-aliasing does not make any difference. Full example is uploaded at
https://godbolt.org/z/We99i_
It seems to work correctly with gcc 8.x and the gcc trunk on goldbot.org.
Thank you.
