float fhackvalue1 = 0, fhackvalue2 = 0;
Confidence filling variable names eh..

Going to need to know more details about the system you are using and what you used to compile this etc.
All I could find was http://stackoverflow.com/questions/12570374/floating-point-exception-sigfpe-on-int-main-return0

Ok. It's Kubuntu 12.04.2 x86, gcc-4.6.3.
Machine - Phenom II X4 955 with Quadro 6000, hardware doesn't matter though - tried on my wife's laptop with intel cpu and AMD video card. Still crashes.
And 3.5-431 works just fine. I can try to go back from 3.5-549 with 3 revisions step until i'll get working build, and then go up by 1 until broken one will be found.

Did you build it on your wife's computer? I'm thinking it's some weird compiler error. Or gdb is lying? Your gdb trace implies the floating point exception is on the initialization of a variable :\

I'll try to build it in VirtualBox with Ubuntu 11.10 then. But... If it's compiler error then why everything before 5xx compiles just fine. Looking at changelog i can't find anything that can affect compiler in any way.

Tried and it changed nothing. Different GCC version but still the same crash
Updated by parlane about 11 years ago
It's just that gdb is saying the error is:
float fhackvalue1 = 0, fhackvalue2 = 0;
Which is weird.

We need some lower level data I think...
try this in gdb:
Print pc:
p/x $pc
Print 3 instructions at $pc:
x/3i $pc
After that we need a register dump too.
info registers
Also after that turn on asm totally with:
layout asm
And give us a dump of that screen. Thanks.
Btw we are on freenode at #dolphin-emu
IRC really helps with debugging these things live.

Try f3528277c4ef
There was a rounding mode that wasn't being set correctly for FPU, could be the cause of this.

- Status changed from New to Fixed
This is fixed with f3528277c4ef, djibb confirmed my suspicions
