Bug#844323: FTBFS on ppc64el

[Breno Leitao]

Source: haskell-zeromq4-haskell
Version: 0.6.5
Severity: serious
Justification: fails to build from source (but built successfully in the past)


The package haskell-zeromq4-haskell is failing to build on ppc64el port
due to the following error:

  [1 of 6] Compiling System.ZMQ4.Internal.Base (
  dist/build/System/ZMQ4/Internal/Base.hs,
  dist/build/System/ZMQ4/Internal/Base.o )
  /tmp/ghc7817_0/ghc_6.s: Assembler messages:
  
  /tmp/ghc7817_0/ghc_6.s:14471:0: error:
       Error: operand out of domain (2 is not a multiple of 4)
  
This is being caused by a wrong assembly code at ghc_6.s

The faulty instruction is:
   
   lwa     29, 2(3)
  
This is a not valid assembly code, because DS filed (2 argument), should
be a word offset. Since a word is 32 bits, it should be multiple of 4.
In this case, it is trying to load an un-aligned word.


I am still trying to discover why this illegal instruction was
generated.
