memory leak without any torrent active?

Dec 22 '22 17:12 ilayanyatto72733

the explanation is missing. There's a long list of "normal block". what's that? Please explain how you come to the conclusion that there's a memory leak. Also please describe how you define memory leak.

1.build simple_client with webtorrent . 2.add the following lines at the beginning of main function. when simple_client quit. it dump the mem leak int main(int argc, char* argv[]) try { #ifdef _MSC_VER { int flags = _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG); flags |= _CRTDBG_LEAK_CHECK_DF; _CrtSetDbgFlag(flags); _CrtSetBreakAlloc(890); } #endif ...................... } 3. output analyse

And do you know what adding that code does and how to interpret the output?

Since you posted this, I'd prefer you do that research to understand whether this is a problem or not.

build with libdatachannel with branch master. without libdatachannel. libtorrent exit gracefully without memleak and deadlock.

memleak with libtorrent run simple_client.exe
