--- Comment #3 from Mikael Pettersson <mikpe at it dot uu.se> --- According to <http://gcc.gnu.org/onlinedocs/gcc-4.8.0/gcc/Zero-Length.html#Zero-Length>, arrays of structures with trailing flex arrays are invalid and rejected. The page also gives an example of that, but changing it to use a char array with either a string literal initializer or a { } one shows that only the { } form is rejected: > cat pr57180-2.c struct foo { int x; char y[]; }; struct foo a[1] = { { 1, "ab" } }; struct foo b[1] = { { 1, { 'a', 'b', '\0' } } }; > gcc -Wall -S pr57180-2.c pr57180-2.c:3:8: error: initialization of flexible array member in a nested context struct foo b[1] = { { 1, { 'a', 'b', '\0' } } }; ^ pr57180-2.c:3:8: error: (near initialization for 'b[0].y') Accepting the a[] initializer while rejecting the b[] one seems broken.
