Description of problem: When building recent hlint, ghc-lib-parser failed to build on F32 armv7hl. Version-Release number of selected component (if applicable): ghc-8.6.5-102.fc32.armv7hl Steps to Reproduce: 1. Build hlint (or ghc-lib-parser not yet packaged) on armv7hl Actual results: Building library for ghc-lib-parser-8.8.0.20190424.. : [146 of 205] Compiling HsLit ( compiler/hsSyn/HsLit.hs, dist/build/HsLit.o ) ghc: panic! (the 'impossible' happened) (GHC version 8.6.5 for arm-unknown-linux): idInfo p_a1om Call stack: CallStack (from HasCallStack): callStackDoc, called at compiler/utils/Outputable.hs:1160:37 in ghc:Outputable pprPanic, called at compiler/basicTypes/Var.hs:541:34 in ghc:Var Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Expected results: No crash Additional info: To be reported upstream after more investigation.
It looks like hlint can build with -O0 at least for ghc-8.8.4/lts-16 (hlint-3.1.6).
