Does TDM's g++ 4.5.x produce dwarf2 symbols?

I don't know about TDM's g++ 4.5.x, but TDM's g++ 4.6.x do (of course, you'll need to d/l the DWARF version).

I think that I'm using the dw2 version of 4.5.x.

I think that I'm using the dw2 version of 4.5.x.

OK - the final DrMemory release with official MinGW support is out. I did a small sample:

Code

#include <cstdlib> // malloc
#include <iostream>

void func2(int* the_old_i, int the_new_i)
{
  std::cout << "Now in func2!" << std::endl;
  *the_old_i = the_new_i;

  std::cout << "Now leaking " << sizeof(double) << " bytes w/ malloc..." << std::endl;
  double* d = static_cast<double*>( malloc(sizeof(double)) );
}

void func1(int* i)
{
  std::cout << "Calling func2()" << std::endl;
  func2(i, 42);

  std::cout << "Now leaking 42 bytes w/ malloc..." << std::endl;
  void* v = malloc(42);
}

int main(int argc, char **argv)
{
  std::cout << "Calling func1()" << std::endl;
  int* i = new int;
  func1(i);

  std::cout << "Now leaking " << sizeof(int) << " bytes w/ new..." << std::endl;

  return 0;
}

And that's the report I am getting:

Nice, isn't it???

VERY nice! I have never used it, I will try to download one from http://drmemory.googlecode.com/files/DrMemory-Windows-1.4.6-2.zip and test it.
