Comment(by goldfire):
This panic is also triggered by building GHC with the following in
build.mk:
{{{
GhcLibWays = v p dyn p_dyn
}}}
Here is the error:
{{{
...
rts_dist_HC rts/dist/build/posix/Signals.
rts_dist_HC rts/dist/build/posix/TTY.
rts_dist_HC rts/dist/build/Apply.hc
addFlag by -C on the commandline: Warning:
The -fvia-C flag does nothing; it will be removed in a future GHC
release
ghc-stage1: panic! (the 'impossible' happened)
(GHC version 7.7.20121002 for x86_64-apple-darwin):
pipeLoop: at phase As but I wanted to stop at phase HCc
}}}
If it matters, I'm compiling on Mac OS 10.7.5 and using GHC 7.6.1.
