core dump in ubuntu22.04

[MDGSF]

os: ubuntu22.04
libhv: 1.3.3
openssl: openssl-1.1.1t

libhv build command:

cmake -DCMAKE_SYSTEM_NAME=Linux \
      -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_INSTALL_PREFIX="/path/to/libhv-1.3.3/output" \
      -DBUILD_SHARED=ON \
      -DBUILD_STATIC=ON \
      -DWITH_OPENSSL=ON \
      .

I use libhv websocket client to communicate with golang websocket server.

I limit the bandwith to 10KB/s ~ 100KB/s, the client is very likely to core dump.

When I don't limit the bandwidth, everything works fine.

Now, I have temporarily modified the code in hevent.c as follows:

bool hio_is_opened(hio_t* io) {
    if (io == NULL) return false;
    if (io->io_type == HIO_TYPE_SSL && io->ssl == NULL) return false;
    return io->ready == 1 && io->closed == 0;
}

bool hio_is_connected(hio_t* io) {
    if (io == NULL) return false;
    if (io->io_type == HIO_TYPE_SSL && io->ssl == NULL) return false;
    return io->ready == 1 && io->connected == 1 && io->closed == 0;
}

bool hio_is_closed(hio_t* io) {
    if (io == NULL) return true;
    if (io->io_type == HIO_TYPE_SSL && io->ssl == NULL) return true;
    return io->ready == 0 && io->closed == 1;
}

but this maybe not a good idea.

io->closed is already set to 1 before hssl_free. Can you print io->closed value?
