Arm: checkProddableBlock: invalid fixup in runtime linker
Just started getting this in the last week or two, but only just now got a chance to investigate more fully.
Any use of GHCi or TH will result in an error like:
ghc-stage2: internal error: checkProddableBlock: invalid fixup in runtime linker: 0x41380050 (GHC version 7.11.20151122 for arm_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Aborted
As a consequence, there are now over 500 failing tests on Arm.
I thought this may have been a consequence of all the recent work on
rts/Linker.c so I checked out git commit 20e30d5f (the one just before the dreaded commit 04e83666 which seemed to kick off a bunch of heavy rework in this file) but that revision causes another, even more mysterious linking failure.
From what I have seen, this only affects 32 bit Arm.
