Today I just realized that in DMD optimize flag does not imply inlining, therefore I promptly added the "inline" to my dub build settings and recompiler, expecting to see speedups in my code execution.
To my surprise, I could not see anything at all: all that I get now is a blank screen.

The rendering code uses an old-ish version of gfm-sdl, but I did not find any issue related to compiler swirches.
Any idea about what might be happening/any suggestion on how to debug this?

If you can write a script which can compare the behavior of two builds of your program to return 0 if they differ or 1 if they are identical, you could plug it into DustMite. Write a test script which builds your project with and without -inline, and compares the output. DustMite would then reduce it to the smallest program the output of which differs depending on whether it was built with -inline.
