winedbg, trace output

A floating-point exception causes the executed program to abruptly end.

Backtrace excerpt:
=>1 0x7efce47a in libm.so.6 (+0x847a) (0x7bbfe5f4)
  2 0x7e88c090 DSOUND_RecalcVolPan+0xf0() in dsound (0x7bbfe644)
  3 0x7e89b0a6 DSOUND_Calc3DBuffer+0x4d6() in dsound (0x7bbfe754)

http://source.winehq.org/source/dlls/dsound/mixer.c?v=wine-0.9.47#L42

In the log, we can see the trace level message:
trace:dsound:DSOUND_RecalcVolPan (0x2167514)
trace:dsound:DSOUND_RecalcVolPan Vol=-301 Pan=-2147483648
meaning the line:
TRACE("left = %x, right = %x\n", volpan->dwTotalLeftAmpFactor,
volpan->dwTotalRightAmpFactor);
is never reached.

The function is also logged at earlier points and working, e.g.:
trace:dsound:DSOUND_RecalcVolPan (0x2167514)
trace:dsound:DSOUND_RecalcVolPan Vol=0 Pan=0
trace:dsound:DSOUND_RecalcVolPan left = ffff, right = ffff


Reproduced in Symphonic Rain (app db entry pending), when clicking on the "Game
Start" main menu option.
