Hi,

the update from dmc 8.38.9n to 8.40.2n introduced a problem with the stlsoft example form ddj rectarr.cpp. Just in case I have added th file ...

In both cases it's the same stlsoft lib which comes with the 8.38 CD version. Only the compiler was updated.

D:\mario\src\cc\palooza\speed4>dmc -DSTRINGTOK_STLSOFT -o+speed -Id:\mario\dm\st
lsoft -odmc_rectarr.exe rectarr.cpp
link rectarr,dmc_rectarr.exe,,user32+kernel32/noi;

Thanks in advance

I'm pretty sure this is a flaw with DMC++'s handling of static initialiser objects (aka Schwarz Counter's). I've mentioned it before to Walter, and there was a workaround built into various headers - look for s_performance_counter_class_constructor in winstl_performance_counter.h - but it looks like 8.40 makes the problem even worse, as the workaround no longer works at all.

If I can isolate it down sufficiently, I'll post a sample bug on the C++ newsgroup, and hopefully a fix can go in 8.41.

For the moment, the answer is simply to comment out both definitions of s_performance_counter_class_constructor in winstl_performance_counter.h. (There's also a similar use of initialisers in winstl_high_performance_counter.h.)

Cheers

Matthew

I wasn't really able to parse the bug here, but if it's something along the lines of "static objects don't get constructed", e.g.:

---- myfile.cxx ----
#include <iostream>

struct wombat
{
  wombat(int c_arg) {
    std::cout << "wombat ctor, carg = " << c_arg << std::endl;
  }
  ~wombat() { };
};

static wombat private_marsupial_thingy(1);
---- end of file ----

In the 8.38 compiler, "wombat ctor, carg = 1" wasn't printed b/c static objects' ctors didn't get called. The workaround is to use anonymous namespaces, e.g.:

namespace {
  wombat private_marsupial_thingy(1);
};

or upgrade to 8.39.
