Hello,

I am hitting a rather uncomfortable bug that causes runtime to start internal busy-waiting at around:

#0 scheme_block_until(_f=<syncing_ready>, fdf=<scheme_syncing_needs_wakeup>)
   at ../src/thread.c:5199
#1  do_sync (name="sync", with_break=0, with_timeout=0)
   at ../src/thread.c:7109

It goes through ../src/thread.c:5190, which Matthew mentions in one of his recent patches.

The code that manages to trigger this have been written under NDA and cannot be published. I have not yet managed to reproduce the issue separately, but it seems that this might not be the only instance:

(09:28:36 PM) m4burns: Mordae: I'm having a similar problem somewhere in `inflate`. Haven't applied a debugger yet, but there's certainly no busy waiting in the script.

I am stuck and would like to ask for your help.

Best regards,
Jan Dvorak
