lowlander 2024-09-17 04:45 developer ~0076995	No method to reproduce, will reopen if this happens again.

lowlander 2024-09-17 15:28 developer ~0077003	It happened again on 3054. Log added (occurs at end of log).

Ludek 2024-09-17 18:58 developer ~0077017	The log is really huge (more than 3 millions of lines) and at the end I really see "Invalid pointer operation" when writing to Z:\MediaMonkey\Portable\CDPlayer.ini But I can't see the callstack as no crash log has been generated, just freeze log in OutputDebugString when you were closing the massive DbgView ouput.. Going to re-analyze code for the possible fix..

Ludek 2024-09-17 20:05 developer ~0077019	OK, I found a code glitch that probably caused this crash, please re-test => Fixed in 3055

peke 2024-09-19 10:52 developer ~0077060	Verified 3055

lowlander 2024-10-10 04:38 developer ~0077234	Unfortunately no log, but this was seen again on 3062.

Ludek 2024-10-10 15:44 developer ~0077238	ok, it's hard to fix something without log, but I revised the previous logs and found another code glitch that could be the cause.. Fixed in 3063.

rusty 2024-10-15 19:51 administrator ~0077295	Unable to replicate in 3064. Leaving as 'resolved' for LL to reverify.

lowlander 2024-10-15 22:46 developer ~0077303	Tested with 20 discs on 3064 and didn't observe this.
