Thanks. > Note that the crash might have happened some time before the end > of the log. Hmm. It should not crash under strace... please see below. > 953 ptrace(PTRACE_ATTACH, 1035, 0, 0) = -1 EPERM (Operation not permitted) OK, so it actually uses ptrace ;) PTRACE_ATTACH fails because this child is already traced by strace, I guess. So does Starcraft crash this way? Or does it fail in some other way? And just in case... perhaps wine does some logging too?
