Thanks for the report.  It's not so much breaking stdout, but rather
that the executable is not recognized as Cygwin executable due to a dumb
mistake I made when computing the size of a section.  Fixed in CVS.

1.7.12 breaks stdout of upx packed executables

[Roland Schwingel]

Hi...

Just updated to 1.7.12 and found one regression. If you have upx packed 
executables (upx from cygwin distribution) the stdout of the packed 
executable is broken now.

Try the following from mintty:
upx --best /usr/bin/tar.exe -o /tmp/tar.exe
/tmp/tar.exe

You will notice that when you invoke the compressed /tmp/tar.exe that no 
output will be sent to the mintty console, while it works if you just 
invoke /usr/bin/tar.exe

It works just fine with 1.7.11. When you decompress the executable using 
upx -d it will start to work again.

This is not specific to tar, but to any exe I have seen right now.

Strange,

Roland
