A work around is to use curl to download the archives by hand (into the downloads/ directory) and setting EMSDK_KEEP_DOWNLOADS=1 which re-uses archives that have been downloaded already.

I have a slow internet connection, perhaps storage.googleapis.com is truncating the download and curl, used by the python to perform the downloads, does not notice!

Isn’t wasm’s loop/block structure odd!

Were you able to reproduce this or was it a one off?

[GeneThomas]

Yes, I can reproduce it.

The number of bytes read looks correct (31379384 Bytes).

Can you modify the emsdk.py script to remove the rmfile lines right below the Removing the corrupted zip file. line? Then attach take the zip file from the emsdk/downloads directory and attach it to this ticket?

I have the same issue on my Linux machine. Here is the file that was downloaded: https://limewire.com/d/Glesz#GAYIFaaoHU (link only valid for 1 week). Sorry for using an external website. GitHub doesn't allow attachments of more than 25 MB.
