I'll cc this directly to Jan as well (this is he's code originally).

I'm a ruby newbie myself, but browsing the code this seems to fail at the
first instance when stresstest.rb needs to run the just compiled ecasound
binary (from ../ecasound/ecasound).

The code should handle all the common cases (invalid string returned, no
executable bit set, file not found), but I suspect something less common
happens that causes this check to fail.

I could generate a similar error by doing:
sh> rm ../ecasound/ecasound
sh> mkfifo ../ecasound/ecasound
sh> chmod +x ../ecasound/ecasound
sh> ./stresstest.rb

The error message is identical, so I think I'm on to something. Please
check what the ecasound binary really is (when you can reproduce the
issue). Is the file the actual binary, or perhaps some linker script or
other build process intermediaery?
