| 04:11.05 | Twingy | that's what I said |
| 04:11.24 | Twingy | 10 mil == 0.01" |
| 04:11.34 | louipc | ah I'm not familiar with that terminology usage |
| 04:12.29 | louipc | I learned and work with a bunch of british machinists that call it a 'thou' or 'thousandth' |
| 04:13.19 | Twingy | in the land of electronics everything is measure in 'mil' |
| 04:13.33 | louipc | ah |
| 04:14.46 | Twingy | I'll solder it on sunday |
| 04:15.01 | Twingy | will be easy |

| 19:18.55 | louipc | hello |
| 19:35.37 | brlcad | howdy louipc |
| 19:37.11 | louipc | I was looking at g_torus.c to try and figure out what was going on :/ no clue |
| 19:37.37 | brlcad | really? |
| 19:37.58 | brlcad | all the g_*.c's are pretty simple -- set of callback routines |
| 19:38.02 | brlcad | unless you mean the actual math |
| 19:39.18 | brlcad | g_xxx.c will give you an idea of the overall structure |
| 19:39.22 | louipc | I did another trace that has more detail it looks like it shouldn't get to the line that the error is at |
| 19:39.25 | louipc | http://pastebin.archlinux.org/11584 |
| 19:39.29 | louipc | ok |
| 19:40.38 | brlcad | ray-tracing generally involves just three or so of he routines, a prep routine called before all the rays first, then a hit/shot routine that actually evaluates a ray against the primitive, and a normal routine that reports on the curvature (so it shades correctly) |
| 19:41.04 | brlcad | ahh, right -- you had the crash |
| 19:41.31 | brlcad | I have a big patch here that might actually fix the problem if it's what I think might be going on |
| 19:41.44 | louipc | aah sweet |
| 19:42.16 | brlcad | that's a BIG if |
| 19:42.33 | brlcad | it shouldn't be happening at all, even with non-ieee math |
| 19:42.43 | brlcad | did you compile optimized or with extra compilation flags? |
| 19:42.59 | *** join/#brlcad Laniakea (i=clock@77-56-106-16.dclient.hispeed.ch) |
| 19:43.00 | louipc | a lot of this is over my head, I just thought I might see if something looked off I've been able to fix other things like that |
| 19:43.32 | louipc | well that latest trace I turned off optimized ... it should be just plain then |
| 19:43.51 | brlcad | and it *still* crashed? |
| 19:44.03 | louipc | yep |
| 19:44.05 | brlcad | wow |
| 19:44.52 | brlcad | try applying this patch |
| 19:44.54 | brlcad | http://bzflag.bz/~sean/smallint.patch |
| 19:45.01 | brlcad | patch -p0 < smallint.patch |

| 20:09.30 | brlcad | geez, still don't get that crash, even with bad math unless the routines are returning NaN or something |
| 20:09.35 | louipc | what's fastf_t? |
| 20:09.41 | brlcad | that line it's crashing on is simply: 3.14159265358979323846 / .15692964165835220337 |
| 20:10.08 | brlcad | acos(1 - 0.26000000000000001) --> -.83307035834164779663 |
| 20:10.34 | brlcad | + .99 --> .15692964165835220337 |
| 20:10.44 | brlcad | fastf_t is double |
| 20:11.13 | brlcad | on most systems at least, potentially could be a float but that's on really old/obscure systems |
| 20:16.54 | louipc | hmm I see yeah it's odd |
| 20:20.35 | brlcad | the only thing that leaves if the stack isn't simply stomped (which doesn't seem to be the case in the backtrace) is that acos() is broken or bn_pi is corrupted (by some earlier problem) |
| 20:20.57 | brlcad | if you have it crash again, try "p bn_pi" if it crashes |
| 20:22.06 | louipc | in gdb right? |
| 20:22.10 | brlcad | right |
| 20:22.15 | louipc | ok |
| 20:22.19 | brlcad | but try the patch first, just curious if it makes any difference |
| 20:22.32 | louipc | it's building now |
| 20:22.49 | brlcad | shouldn't now that I see the values in your trace |
