I'm trying to reindex with the following command

litecoin-qt.exe -reindex

or

litecoind.exe -reindex

and the process deterministically crashes with

Exception thrown at 0x0000000000DA9A23 in litecoin-qt.exe: 0xC0000005: Access violation reading location 0x0000000000000004.

and the state:

  • Number of blocks left: 1386142
  • Last block time: So Aug 20 08:10:39 2017
  • Progress: 6.33%

I'll try to downgrade the client and will add info here.

Expected behavior
No access violation

Actual behavior
Exception thrown at 0x0000000000DA9A23 in litecoin-qt.exe: 0xC0000005: Access violation reading location 0x0000000000000004.

in state:

  • Number of blocks left: 1386142
  • Last block time: So Aug 20 08:10:39 2017
  • Progress: 6.33%

with both, v0.21.2.2 and v0.21.2

To reproduce
run the command
litecoin-qt.exe -reindex

Can reliably reproduce every time.

litecoin.conf is empty.

System information
Tested so far with

  • Litecoin Core v0.21.2.2 Release
  • Litecoin Core v0.21.2 Release

from https://github.com/litecoin-project/litecoin/releases

on

Edition	Windows 11 Pro
Version	22H2
OS build	22621.3155
Experience	Windows Feature Experience Pack 1000.22684.1000.0

Processor	AMD Ryzen 9 7950X 16-Core Processor               4.50 GHz
Installed RAM	64.0 GB (63.1 GB usable)
System type	64-bit operating system, x64-based processor

KINGSTON SFYRD4000G

extra info
The debug.log doesn't show the exception.
Its last entry is
2024-03-10T15:43:40Z UpdateTip: new best=fd4bc7ebe60a72248aa218de4caf82f6fd32a9613331f34beea9980059b7b00d height=1261660 version=0x20000000 log2_work=67.564697 tx=11494846 date='2017-08-20T12:34:02Z' progress=0.063369 cache=85.4MiB(227175txo)

The process just silently dies. I looked at the dumps and attached Visual Studio to see the exception.
It might be helpful to get the PDBs of the build to narrow down the location but i couldn't find them and haven't succeeded creating my own build yet.

Couldn't find the config.log.

Reindexing with v0.17.1 seemed to work well.

Also opening afterwards with v0.21.2.2 worked but debug.log showed errors which don't look good:

Rolling back to the data from after reindexing with v0.17.1 and trying with v0.18.1.

No errors but a lot of warnings in the debug.log:
