Wow. Learn something every day. No wonder ELF is so much more popular in the open source community. > > It's an unlucky case.

So the cygwin DLL is likely to be the only PE/COFF dll that strip ever encounters with a section marked as debug in the middle of a file? If it is ever expected that other DLLs will have the same property, then yes, strip should be taught to not strip intermediate debug sections; but if it is just cygwin1.dll, I can live with the rule of thumb of "don't do it if it hurts". - -- Life is short - so eat dessert first!
