Bishonator reports the following problem in the forums:

Apparently the following code reproduces it:

{

    nvtt::Compressor *c1 = new nvtt::Compressor();
    c1->enableCudaAcceleration(true);
    printf("test: cuda = %s\n", c1->isCudaAccelerationEnabled() ? "true" :
"false");
    delete c1;
}

nvtt::Compressor compressor;
compressor.enableCudaAcceleration(!nocuda);
printf("perf: cuda = %s\n", compressor.isCudaAccelerationEnabled() ? "true"
: "false");

And it outputs to screen:
test: cuda = true
perf: cuda = false
