Hi,
I recompiled some dependencies of my project like this (to see more cost
centres):
{{{
cabal install --reinstall --ghc-option=-auto-all OpenGL GLUT ftgl
}}}
then while trying to recompile my project:
{{{
cabal clean
cabal install --enable-library-profiling --enable-executable-profiling
--disable-documentation --ghc-options="-O2 -ddump-simpl-stats"
}}}
the first (non-profiling) build succeeds, but then during the profiling
build:
{{{
ghc: panic! (the 'impossible' happened)
