Confirmed. Here's a slightly simplified testcase:
-----------bar.h------------
typedef struct {
unsigned : 16;
unsigned : 16;
} foo;
-----------bar.c------------
#include <stdio.h>
#include <bar.h>
foo bar(unsigned i)
{
printf("bar: i is %u.\n",i);
foo myfoo;
return myfoo;
}
-------------foo.cc------------
#include <stdio.h>
#include <bar.h>
extern "C" foo bar(unsigned int);
int main(void)
{
foo myfoo;
unsigned i = 3;
printf("foo: i is %u.\n",i);
myfoo = bar(i);
return 0;
}
-------------------
tmp/g> gcc -I. -c bar.c
tmp/g> g++ -I. -o foo foo.c bar.o
tmp/g> ./foo
foo: i is 3.
bar: i is 1289971520.
Something appears to go wrong when calling the extern "C" function...
This is a wrong-code regression on valid code.
