[Bug 46126] New: Provide more exception context information in ARM64 implementation of raise_exception ()
https://bugs.winehq.org/show_bug.cgi?id=46126
Bug ID: 46126 Summary: Provide more exception context information in ARM64 implementation of raise_exception() Product: Wine Version: 3.20 Hardware: aarch64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs@winehq.org Reporter: focht@gmx.net Distribution: ---
Hello folks,
as it says.
Currently the diagnosis via tracing is very limited because the exception code, exception address and register context is not dumped at all.
Example:
