Hi folks.
The code below is ICE-ing in C++:
typedef struct {
unsigned char dir;
int data[];
} AiDefaultRailBlock;
static const AiDefaultRailBlock _raildata_ai_0 = { 1, { 0, 4 } };
According to our docs, this is valid under flexible arrays:
http://gcc.gnu.org/onlinedocs/gcc-4.0.2/gcc/Zero-Length.html#Zero-Length
Mark has a note on the PR that says C++ does not support flexible arrays,
but our documentation seems to imply we do. The discussion of
zero-length arrays (and flexible arrays) is under the "Extensions to the
C Language Family" section.
Should we specify that flexible arrays are not supported in C++?
How about:
struct foo {
int bar;
int a[];
} hot;
This compiles fine with either C or C++. Shouldn't we disallow this
initialization in C++ if we don't support flexible sized arrays?
