ghci crashes with .o mismatches
Basic recipe is:
-
have multi-file program, compile with ghc --make (this creates some .o files in course of compilation)
-
edit some files and then run ghci and attempt to load main file with :l file.hs
-
ghci tries to load some of the compiled .o files, and crashes.
Workaround is to delete the .o's before running ghci.
Loading package binary-0.4.2 ... linking ... done.
<interactive>: internal error: loadObj: can't map `Records.o'
