gcc (Debian 11-20210130-1) 11.0.0 20210130 (experimental) [master
revision 4d31df40899:799f8820257:2900f2f2c5fb234678eb8b76564e5994ec5970b9]
gcc -fanalyzer for the sample code below gives false positive results.
If I remove field ref from struct marker, no problem is reported.
Best regards

So ccp3 is doing it.
Visiting statement:
quo_lo_52 = floorf (_51);
