-----------------------------------+----------------------------------------
This bug seems to be reproducible on Linux, Windows, and OpenBSD, at
 least.

 In the included package, run ./build.sh, which will build and run a
 program as follows:
 ghc -lz -threaded --make unstuff.hs -o unstuff
 ./unstuff trace.dat

 The program forks a lot of OS threads. After several seconds of running,
 it dies with:
 ---------------------
 unstuff: user error (ORANGE ALERT: 0s, 4s, SrvServerInfo, ix1: 6, size:
 49722)

 unstuff: internal error: scavenge_stack: weird activation record found on
 stack: 64384
     Please report this as a bug to glasgow-haskell-bugs@xxxxxxxxxxx,
     or http://www.sourceforge.net/projects/ghc/
 ---------------------

 The first message is simply an error printed by the program reporting that
 it took too long to compute a result.
