rzipped +relay,+seh,+winsock,+heap log of downloader running and crashing

The peer-to-peer downloader
( http://installers.crypticstudios.com/STO_Demo_Installer.exe )
starts fine, prompts for the directory to download to,
and puts up a progress window, but after a minute crashes with
Unhandled exception: illegal instruction in 32-bit code (0x00557185).
and a not very useful stack.

This was first mentioned in July by http://jan.saell.org/blog/archives/1009

+heap seems to make it crash sooner with

Unhandled exception: page fault on read access to 0xfeeefeee in 32-bit code
(0xfeeefeee).
Backtrace:
=>0 0xfeeefeee (0x0083e9ac)
  1 0x00426aed in sto_demo_installer (+0x26aec) (0x0083e9e0)

The thread that crashed seems to be in a window proc,
and another thread seems to be in GetQueuedCompletionStatus.
