--- Comment #20 from Przemyslaw Wirkus <wirkus at gcc dot gnu.org> --- Just a heads-up: I would like to suggest backport for this patch to GCC 9 and 10. Quoting Vladimir: > The bug is actually severe and should be classified as P1 Currently patch applies cleanly for both gcc-9 and gcc-10 branches. I will firstly bootstrap both toolchains (9&10) with this change and run some tests. After I'm done and all is OK I will properly ask for backport. Again, Vladimir, thank you for the fix!
