For all official releases, OpenTTD collects the Breakpad Symbols (SYM-files) and Microsoft's Symbols (PDB-files), and publishes them on our own Symbol Server (https://symbols.openttd.org).
These symbol files are needed to analyze crash.dmp
files as attached to issues by users.
A crash.dmp
is created on Windows, Linux, and MacOS when a crash happens.
This combined with the crash.log
should give a pretty good indication what was going on at the moment the game crashed.
In MSVC you can add the above URL as Symbol Server (and please enable MSVC's for all other libraries), allowing you to analyze crash.dmp
.
Now simply open up the crash.dmp
, and start debugging.
The best tool to use is minidump-stackwalk
as published in the Rust's cargo index:
cargo install --locked minidump-stackwalk
For how to install Rust, please see here.
Now run the tool like:
minidump-stackwalk <crash.dmp> --symbols-url https://symbols.openttd.org
For convenience, the above Symbol Server also check with Mozilla's Symbol Server in case any other library but OpenTTD is requested.
This means files like libc
, kernel32.dll
, etc are all available on the above mentioned Symbol Server.
