http://bugs.winehq.org/show_bug.cgi?id=59672 --- Comment #10 from axis6404@proton.me --- I noticed a recurring discrepancy in the logs, such as around line 1414 of doaxvv9003-20260418.txt. Both winhttp:read_data and the "dwStatusInformationLength" in WINHTTP_CALLBACK_STATUS_READ_COMPLETE(0x80000) are occasionally 8193, even though only 8192 bytes were reported as available. 06e8:trace:winhttp:WinHttpQueryDataAvailable ... ... 06e8:trace:winhttp:query_data_available 8192 bytes available ... 06e8:trace:winhttp:WinHttpReadData ..., ..., 8193 (sample code: https://learn.microsoft.com/windows/win32/api/winhttp/nf-winhttp-winhttpquer...), ... ... 06e8:trace:winhttp:read_data 8193 bytes read <--- here!!!!!!!!!!!! 06e8:trace:winhttp:send_callback ..., 0x80000, ..., 8193, ... <--- here!!!!!!!!!!!! I suspect 8192 is the correct value. Could you check if this 1-byte overflow is causing the issue? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
