WOW! I really hope that this will fix the problem. I will check it
tomorrow, but can you please let me know what does this flag do?
check on the internet, its a well known gotcha which has been fixed in
VS2010. basically, it disable some iterator checking which is strangely
active even in release mode.
Another question! Do I have to add the line
#define _SCL_SECURE 0
to all my header and code sources even source of GMM++ or just on my
own source files or even on file is enough?
easiest way is to add /D"_SCL_SECURE=0" (or the like) to your command
line when compiling your code *and* gmm (if its not header only?)
or add it first in all the C++ files.
What about those pragmas you mentioned?
check msdn. if needed add, they must be defined before including the gmn
headers.
Thanks

hi,
try to define _SCL_SECURE=0 (warning ABI incompatible so all the code
you link must use this flag)
for code using the stl heavily, it can result in 100x speedup.
perhaps also:
#pragma inline_recursion
#pragma inline_depth
and check all the optimisation are on.
