Confirmed.  The following fails with -O2 -m32:

typedef unsigned long ULONG;
void iwos_ErrorMessage(long error, const char * const file_name,
   ULONG line_num, const char * const message);
class AbcA2d {

double y;

AbcA2d ClampPoint2d(const AbcA2d  rPoint) const;
AbcA2d GetMax() const { return m_vMax; }
AbcA2d GetMin() const { }
AbcA2d Evaluate(double dNormalizedX, double dNormalizedY) const;
};
inline AbcExtent2d::AbcExtent2d(const AbcA2d  rMin, const AbcA2d  rMax)
{
if (rMin.x  rMax.x || rMin.y  rMax.y)
  {
long sErr = (1007);
if (sErr != 1000)
  iwos_ErrorMessage(sErr,(const char * const)__null,
0,(const char * const)__null);
  }
else
  {

m_vMax = rMax;
  }
}
inline AbcA2d AbcExtent2d::ClampPoint2d(const AbcA2d  rPoint) const
{
AbcA2d sRet = rPoint;
if (rPoint.x  m_vMin.x)
  sRet.x = m_vMin.x;
return sRet;
}

const
{
AbcA2d sRet;
sRet.x = m_vMin.x + dNormalizedX * (m_vMax.x - m_vMin.x);
sRet.y = m_vMin.y + dNormalizedY * (m_vMax.y - m_vMin.y);
return ClampPoint2d(sRet);
}
class AbcAbcdTracer {
AbcExtent2d m_vUVDomain;
virtual long TestIsoAbcde(AbcZyParamType eZyParam, double dParam,
  int  rbZyxIsSolution);
virtual int DoesPointLieOnAbcde(AbcA2d  rUV, int bRefinePoint) const;

  ;
  }
}

Is this an IRA bug?

Yes, it is an IRA bug.  Code processing calls to functions can throw is
lost in IRA.

I'll submit a patch tomorrow.
