I haven't been able to reproduce it. It's the plug-in that seems to be a bit buggy - e.g. when it is in the plugins folder and out_sqr.dll isn't, there is a crash during app start-up (in SDB and in WinAmp). |

I've been trying to get to the bottom of this, and I think it may have to do with a problem with the output plugin rather than the general plug-in (I'm not sure though). I've tested the sqrsoft output plug-in on three different machines: 1) Works but crashes on exit when the ACF controller is used 2) It crashes as soon as the user tries to configure the plugin (regardless of whether or not ACF controller is installed) 3) Same as 2) On the latter 2 machines, the bug occurs as follows: -select the sqrsoft output plugin and make it active -click the configure button -->'Invalid floating pointer operation' -->then, 'Access violation error' -->at this point, SDB is unresponsive (or a dialog has appeared and there's no access to it--perhaps that's related to the problem?!?) -Right click the SDB tray icon and click 'close' -->then another error message appears 'Songs-db has generated errors and will be closed by Windows' Note: on all three machines, these errors do not occur with WinAmp. Note: machines 2 and 3 are laptops with 1024x768 resolution, both running w2k (I doubt this is relevant, but just in case...). The attached trace is from machine #2: 1-78: Startup 79-80: Click 'Configure' for the sqr output plug-in 81-end: Close SDB via right click of tray icon edited on: 07-07 11:13 |

I have tried it, but it seems I can do nothing here, the bug is in the plug-in. It is definitely triggered by something in SDB, which isn't incorrect, but unexpected for the plug-in and doesn't handle it. If you have some contact to the developers, we can asked them to look at it (I think it will be quite simple for them to locate the problem), but from my side it would require very long time and the result is doubtful. |

Re-opening and assigning to Rusty to see if the authors can fix it. |

Well problem is in Plugin as plugin do not destroy Form Note To Jiri: in General plugin Quit Function there is no Destroy only Close. When DLL loaded and those two are executed: Application.CreateForm(TMainForm, MainForm); MainForm.ParentWindow := Plugin.hwndParent; // Set Winamp/MM as ParentWindow Quit Function must have MainForm.Destroy; Not Only MainForm.Close; Bug Only exists in some cases under win9x, but allways under XP |

|
Note: in testing various plugins, it appears that this occurs in many other alarm plugins and in global hotkey plugins. |
|
|
If needed ican provide example of both cases. |

I just experienced this 'Invalid pointer operation' on close with build 1692. No special plugins installed or enabled. Elog submitted. |

Rusty, the original report is 10 years old and I doubt that it is related, why do you think so? Did you really sent the ELF, I haven't found any from you. Could you attach it? |
