Ticket #3720 (closed bug: wontfix)
unknown symbol `_GLOBAL_OFFSET_TABLE_' when loading module
I get the following, which is caused by a bug in ghci, which probably results from ghci reusing .o files when it should not.
Util.hs is a user-defined file on which the module which is currently being loaded (Main.hs) depends.
<interactive>: ./Util.o: unknown symbol `_GLOBAL_OFFSET_TABLE_'
If I remove all the .o files, the module happily loads in ghci.
