[Adobe-source-devel] FW: ASL crash

[Foster B. <fbr...@ad...>]

FYI -- Sean, any interest in taking a look at this?

I have the ASL crash in its own project, 20 lines, crashes in the same way -
when stuffing the fourth element into 'aDict':

#include <adobe/dictionary.hpp>
#include <adobe/name.hpp>

int main (int argc, char * const argv[]) {

adobe::dictionary_t aDict;

adobe::version_1::static_name_t one("one");
adobe::version_1::static_name_t two("two");
adobe::version_1::static_name_t three("three");
adobe::version_1::static_name_t four("four");

aDict[one].assign((adobe::any_regular_t((double)1.0)));
aDict[two].assign(adobe::any_regular_t((double)2.0));
aDict[three].assign(adobe::any_regular_t((double)3.0));
aDict[four].assign(adobe::any_regular_t((double)4.0));


    return 0;
}

[Update: This works with gcc 4.0 and 4.2; it crashes with llvm-gcc-4.2]

The failure is in boost::compressed_pair. I was able to reduce the  
test to this:

---
#include <boost/compressed_pair.hpp>

namespace {

struct empty_base_t { };
struct empty_t : empty_base_t { };

typedef boost::compressed_pair<empty_t, int> data_t;

} // namespace

int main () {
   data_t x;

   x.second() = 0;
   x.first() = empty_t();
   assert(x.second() == 0);

   return 0;
}
---

I haven't yet figured out why compressed_pair is failing - but it  
appears to be  a compiler bug.

I narrowed it down to the following - clearly a compiler bug. I'll  
file a Radar report.

Sean

----
#include <cassert>

namespace {

struct empty_base_t { };
struct empty_t : empty_base_t { };

struct pair_t : empty_t {
   empty_t& first() { return *this; }
   int& second() { return second_m; }

   int second_m;
};

} // namespace

int main () {
   pair_t x;

   x.second() = 0;
   x.first() = empty_t();
   assert(x.second() == 0);

   return 0;
}
