Definitely not.

I have one suspicion regarding a possible reason: you're not using
-gstabs, and you're compiling C++ code. That's not a very good
combination, generally. The difference in format of debugging
information might cause GDB to be very slow at finding the source line
corresponding to a particular program counter register value.

You're overreacting a bit, I think. Just because it seems to be a bit
slower than you expect doesn't mean it's not working correctly.

To give it a fair chance, you also should not be testing the program
in single-step mode. Try

	gdb test.exe
	gdb > run

or

	gdb test.exe
	gdb > b main
	gdb > run
	gdb > continue

for a change.
