Bug report: g++ 2.96 on Linux |

Hello,
We used g++ 2.96 to build our product on Linux RH 7.2.
We could build our product without any build error. But soon as we try to run
the optimized build, we got a core-dump. The debug build never got the
core-dump.
The bug is causes by some incorrect because of which
a constructor for mathUInt64 which takes a double input does not work right.
Here is the problem code:
mathUInt64::mathUInt64(const double theValue, const char* debugString)
: baseObj(debugString)
, m_Value((UINT64)theValue)
{
agAssert (theValue >= 0);
}
Here is the workaround:
Just putting a printf in the constructor changes the optimization and things
start working fine as the following code.
mathUInt64::mathUInt64(const double theValue, const char* debugString)
: baseObj(debugString)
, m_Value((UINT64)theValue)
{
printf ("Constructing theValue: %lf m_Value: %lld\n", theValue, m_Value);
agAssert (theValue >= 0);
}
This is a temporary solution.
Please give us a right solution to fix this problem.
Thanks,
Tom
