Bug 23345 – ImportC: out of order designated initializers initialize to wrong value

The issue is demonstrated with the following C program: struct String { unsigned long length; const char* ptr; }; extern void abort(void); int printf(const char*, ...); void assert_(_Bool cond, int line){ if(!cond) { printf("assertion at line %d failed\n", line); abort(); } } int main(){ struct String a = { .length = sizeof("hello")-1, .ptr = "hello", }; struct String b = { .ptr = "hello", .length = sizeof("hello")-1, }; assert_(a.length == 5, __LINE__); assert_(b.length == 5, __LINE__); // this one fails return 0; }

A much simpler test case: struct S { int a, b; }; struct S s = { .b = 3, .a = 2 }; The initialization is a=0, b=3
