Is it possible that the String you are passing to uLog contains unevaluated calls to uLog itself, which would thereby create a deadlock as uLog tries to take the MVar that is already being held by the same thread?

thread blocked indefinitely in an MVar operation in unsafePerformIO
Hi. I'm having a problem calling logM from hsLogger inside unsafePerformIO. I have described the problem in Haskell-cafe, so I'll avoid repeating it here: http://www.haskell.org/pipermail/haskell-cafe/2012-July/102545.html I've had this problem both with GHC 7.4.1 and 7.4.2. Do you have any suggestion?

Hi. I just tested building ghc6-6.12.1-4_powerpc with a registered build, that is, without those lines from debian/rules that make an unregistered build, and got a segfault just after running inplace/bin/ghc-stage2 --interactive.

I suppose the platforms that you listed this is not supported and GHCi (or more precisely the part of GHCi that requires the byte code interpreter) is not built. Thanks for your answer.
