ppci-cc: wrong initialization of nested structs

[tstreiff]

With the following declarations:

struct S1 {
int a;
int b;
};

struct S2 {
int a;
int b;
union {
int c;
int d;
};
struct S1 s;
};

struct S2 v = {1, 2, 3, {4, 5}};

v.a is 1, v.b is 2, v.c and v.d are 3, but v.s.a and v.s.b contains garbage.

This is correct, right, since the union has superfluous initializers, and the last 5 is discarded. What do you expect here?

[tstreiff]

We should get:
v.a = 1, v.b = 2, v.c (and v.d which memory with v.c) = 3, v.s.a = 4, v.s.b = 5

[windelbouwman]

Ah, yes, I see, sorry, I misread the example, you are absolutely right here!

[windelbouwman]

My fear was that the parsing and semantics was wrong, but actually it was a simple fix in the codegenerator for this code. See commit 81b66a1

Example 00050.c now passes.

@tstreiff do you think this bug can be closed?

[tstreiff]

Yes, the test is now OK!
