--- Comment #13 from Christophe Lyon <clyon at gcc dot gnu.org> --- (In reply to Christophe Lyon from comment #12) > However, I am probably missing something since with an updated 4.9-branch > and without this patch, I couldn't make the compiler crash: > $ aarch64-unknown-linux-gnu-gcc -S test.c -mbig-endian > test.c:2:15: error: expected specifier-qualifier-list before ‘v4si’ > struct S2823 {v4si a;int b[0];}; Not sure what was wrong with my previous build.... I now managed to reproduce it on the 4.9-branch (r224544). With the patch applied, the ICE disappears as expected. Bootstrapped on x86_64 and aarch64, make check shows no regression.
