ghc-* packages have been quite painful from the beginning on (the deps seem to be very strict based on build ids, which keep on changing on rebuilds - hence always an entire tree needs to be built - terrible situation with the number of ghc* packages increasing as it does) The strict dependency on build ids is required because GHC does not produce a stable ABI for packages. Upstream has been working on that issue for a while but they are not done yet.

A typical build log contains plenty of:
I take it these are random failures. I have seen quite a few of those failures on PowerPC where we know that the code generated by GHC is not correct for a multi-processor/core environment. It seems there is also an issue in x86_64. I will first revert that latest patch to package ghc. If that does not improve the situation I will revert parallel builds for ghc packages in ghc-rpm-macros. -- You are receiving this mail because: You are on the CC list for the bug.

It's interesting that we don't see those errors in https://build.opensuse.org/project/show/devel:languages:haskell. That project has a few transient errors every now and then -- i.e. because a VM malfunctioned or ran out of memory --, but the failure rate is nowhere near 1/3rd of the builds, and I don't recall seeing those error messages Dominique cited at all, really.
Is Factory built with higher parallelism than devel projects? -- You are receiving this mail because: You are on the CC list for the bug.
