Hi,
It's been a few months since I work on "DQuick" at a rate of a few
minutes or hours from time to time. After working professionally
with Java during a year I was really surprise to see D capable to
compete a such language on productivity and providing much more
features than C++.
But because D and his compiler aren't as mature as c++ compilers, it
can be really hard to debug our code, mainly when searching memory
issues, because generated code by DMD isn't compatible with existing
tools (Valgrind, DrMemory).

What about gdc?

I also tried with gdc, and DrMemory and Valgrind doesn't works better
with binaries generated with gdc. (I tried under Windows and Linux).
Here is both trace of DrMemory, first for dmd, second GDC :

Maybe an issue due to the gc?
