Understood. Maybe start a dedicated discussion on gdb-patches with your current findings? Maybe Pedro can give you some pointers, to help us debug and fix this thing? I see that you've already provided a bit of information in the PR itself (https://sourceware.org/bugzilla/show_bug.cgi?id=25939), but perhaps we could start with a summary of the situation, and what you have found so far? For instance, IIUC, this affects debugging of any program on Solaris. Are you still getting the same error? Your observation about a large number of threads being created is interesting, and perhaps deserves to be dug into a little deeper, considering that you think this wasn't happening with a version prior to the multitarget patch series? -- Joel
