--- Comment #14 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > (1) I don't understand what has changed to explain the failures. I still don't know what change between r217514 and r217602 caused it but the reason is that there is now two spaces instead of one in the outputs of the kind: #0 0x66d09 ( ... Thus the failures are gone if the original pattern '\[(\])' is replaced with ' \[(\])'. In order to keep some backward compatibility I have replaced '\[(\])' with ' ?\[(\])' and the failures are gone (I'll attach a new patch ASAP). > I got the latest LLVM here: http://llvm.org/releases/download.html#3.5 > (Clang for Darwin 10.9) and put llvm-symbolizer in my PATH.
