https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99106 --- Comment #7 from CVS Commits --- The releases/gcc-8 branch has been updated by Jakub Jelinek : https://gcc.gnu.org/g:3a51e6261f7d98d54fc370125b1895542c3cdce9 commit r8-10886-g3a51e6261f7d98d54fc370125b1895542c3cdce9 Author: Jakub Jelinek Date: Wed Feb 17 15:03:25 2021 +0100 c++: Fix up build_zero_init_1 once more [PR99106] My earlier build_zero_init_1 patch for flexible array members created an empty CONSTRUCTOR. As the following testcase shows, that doesn't work very well because the middle-end doesn't expect CONSTRUCTOR elements with incomplete type (that the empty CONSTRUCTOR at the end of outer CONSTRUCTOR had). The following patch just doesn't add any CONSTRUCTOR for the flexible array members, it doesn't seem to be needed. 2021-02-17 Jakub Jelinek PR sanitizer/99106 * init.c (build_zero_init_1): For flexible array members just return NULL_TREE instead of returning empty CONSTRUCTOR with non-complete ARRAY_TYPE. * g++.dg/ubsan/pr99106.C: New test. (cherry picked from commit af868e89ec21340d1cafd26eaed356ce4b0104c3)
