Summary0001074: Dr. Watson when GetCPUInfo is called
DescriptionI have a compiled EXE under a VMWARE Windows NT4 session. When I start the application, I get an Error reported by Dr. Watson. The application terminates. I have have tried to debug through the initialization sections of the application. I found that the problem occurs in GetCpuInfo, which is called in the initialization section of JclGraphUtils from within SetupFunctions.
Additional InformationIf I comment out the function, I have no more problem.

procedure SetupFunctions;
{ TODO : Make MMX-Detection independent from Windows-tied code }
{$IFDEF MSWINDOWS}
var
  CpuInfo: TCpuInfo;
{$ENDIF}
begin
  {$IFDEF MSWINDOWS}
  //WIMDC
// GetCpuInfo(CpuInfo);
// MMX_ACTIVE := CpuInfo.MMX;
  MMX_ACTIVE := false;
  {$ENDIF}
  if MMX_ACTIVE then
  begin
    // link MMX functions
    CombineReg := M_CombineReg;
TagsNo tags attached.

 Hi,

This problem is most probably due to a high-speed CPU (>= 2GHz) on the respective system.

Does http://projectjedi.sourceforge.net/issuetracker/file_download.php?f_id=0000252&f_type=bug fix this issue for you?

If not, it would be nice if you could tell exactly how it fails. You could use the JCL Debug Extension (see "examples" directory) to get extended exception information at runtime.

We urgently need user cooperation here, because apparently none of the JCL developers has a system fast enough to reproduce this specific error.
