Once you have those two files, compile with this:
dmd -unittest t1.d bug.d
and then run t1:
./t1
The output you get should look like this:
...
[0, 4, 0, 0, 0, 0, 0, 2, 0, 0, 1, 2, 0, 1, 0, 0]
I get:
...
[0, 4, 0, 0, 0, 0, 0, 2, 0, 0, 1, 2, 0, 1, 0, 0]
Obviously the output is wrong. 'm9' for some reason is getting
overwritten. In my project this caused big problems because there are
other m# with different values, and their values would literally get
copied to m9. Calling inverse() on m9 then would fail because the
other matrices are not invertible. Placing a writeln() in inverse()
helped me realize that what was being passed to inverse() was being
modified somewhere. I'm still now sure how m9 is being modified.
Another point, compiling with this:
dmd -unittest bug.d t1.d
and then running bug:
./bug
doesn't trigger the bug.
I get:
...
[4, 0, 0, 0, 0, 0, 2, 0, 0, 1, 2, 0, 1, 0, 0, 1]
Could someone else please confirm this behavior?
I have used DMD 2.058 64-bit linux.
