I am using Parallels to run Windows, on which I develop software under msys (specifically Mozilla-related code). Since updating to Parallels 4.0, I get the following error during my build: 0 [main] tar 3876 open_stackdumpfile: Dumping stack trace to tar.exe.stackdump make[1]: *** [libs] Error 139 I searched around a bit, and it seems like msys is known to conflict with certain low-level software (specifically there is a known conflict with some Logitech webcam software). See http://readlist.com/lists/lists.sourceforge.net/mingw-msys/0/339.html for one example. I can't be 100% sure that Parallels 4.0 is responsible for the problem, but I went back to an old cloned VM that has always worked and I have the same problem. I am quite confident that the Parallels upgrade is responsible. This is a big issue for me since I use my Parallels VM as my only Windows development environment. I would be happy to provide you with any information you might need to reproduce the problem.
