 > For some reason crash dumps are not collected, even though I followed
 the instructions you linked. I can try building a debug version of GHC and
 give it a go. Is this the right instructions to obtain debug ghc
 https://ghc.haskell.org/trac/ghc/wiki/Debugging/Compiler?

 If you can that would be really handy! as I can't see to reproduce it.

 https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows are the
 packages you'll need installed, then just copy `mk/build.mk.in` to
 `mk/build.mk` and uncomment the `devel2` line.

 Once building finishes, just do

 {{{
 cd ghc
 make re2 GhcDebugged=YES
 }}}

 and it'll relink ghc using the debug runtime.

 you can then run ghci as

 {{{
 inplace/bin/ghc-stage2.exe --interactive +RTS -Dl -RTS 2> linker.log
 }}}

 to dump a linker log. You can also try attaching it to gdb and see if it
 happened to have segfaulted in rts code.
