Comment (by trommler):

 Replying to [comment:12 goldfire]:
 > However, if the comment:1 issue isn't fixed, I think there's more work
 to be done here, no?
 I would like to open a new ticket for the issue in comment:1 because I
 think it is a different issue.

 The undefined symbol in this ticket is in another package whereas in
 comment:1 it is found in one of the objects of the current package. That
 symbol, however, should be resolvable by linking with the previous
 temporary shared object and following the chain of links to the module
 where the symbol is defined. My current hypothesis is some Linux
 distributions modify the defaults of GNU `ld` (and perhaps Gold) and that
 is responsible for the undefined symbol.

 The fix that I have in mind involves checking for a link editor flag
 called `--no-as-needed` (and it must be the link editor we use in the
 installed ghc) and then passing the correct flag to override the default.
 See: https://ghc.haskell.org/trac/ghc/ticket/9186#comment:26 for more
 details on that flag.

 The issue does not affect OSX. That would reduce the scope of the defect
 to only those systems that have a modified` ld` , i.e. some Linux
 distributions.

 I'll create a new ticket with more details tomorrow.
