Using GNU gdb 6.5.50.20060813-cvs, the error I get is "Couldn't get registers: No such process." - this is with follow-fork-mode set to parent. With the original version of gdb (GNU gdb 6.4-debian, from Ubuntu Dapper), I get: thread_db_get_info: cannot get thread info: generic error (as originally reported). So you are somewhere near the error, but not quite there. I've also confirmed the original bug on both i386 and x86_64 Linux. I can replicate this 100% of the time (on my own, large, app, naturally, as having a simple sample to do it would make things much too easy). Get any version of Xara Xtreme from http://www.xaraxtreme.org/ and run it under gdb. Whenever it executes an external program, it hangs under gdb. The easiest case is to install imagemagick, draw anything, then try an export a PSD file. If you've installed from a package, loading any file will do it as the extensible filter system will try executing one of the filters. Alex
