seems to be reproduceable when zooming max out and then zooming very fast in while holding CTRL + SHIFT.

holding CTRL only leads to SIGFPE as well, but when holding SHIFT+CTRL its easier to get the SIGFPE...

 cq = {... p0 = ... {x = -nan(0x7fdbb0) ... }

What camera mode(s) trigger(s) this and on what map(s)? Does it happen when zooming in extremely close to units or features or also when there is only empty ground?


Seems there are a few unrelated NaN sources as well:

modSunColor = { ... z = -nan(0x7fe450)}
ffy = -nan(0x7fdde0) // fy - math::floor(fy)

Overhead (TA) style camera, didn't test others yet.


not sure if a unit in view affects it, seems to crash with and without in view, but didn't crash when zoomed very closely to map.

(crash = SIGFPE this time)

 what map(s)?

no SIGFPE's on other (smaller) maps it seems

Can't reproduce here on that map, maybe zoom-speed isn't high enough. Also, for me pressing CTRL with overhead camera controls the viewing angle, it does not affect speed.

oops, yes CTRL changes view angel for me too. wasn't clear as in the first tries it instantly SIGFPE'd.

SHIFT speeds changing view angel a little up for me.

i'm using a debug build, so maybe this gives the needed slowdown to reproduce this.

 Ah, this line

  const float waterRayLength = math::floor(math::fabs(start.y / std::min(dir.y, -0.00001f)))

generates an FPE when

  start.y = 21481.2246f (possible only on larger maps)
  dir.y = 0.577349603f

since

floor(abs(21481.2246f / min(0.577349603f, -0.00001f))) ==
floor(abs(21481.2246f / -0.00001f)) ==
floor(abs(-2e+09)) ==
floor(2e+09) ==
10752 (!)
