When I run the program under gdb in bash, the first few threads are started, then gdb suspends itself and I need to call 'fg' to resume execution, i.e. the whole thing looks like e.g.: [674]$ gdb ./umc.vx GNU gdb 6.3.0.20050704-cvs ... [New LWP 27] UMC1-1-> [07-05 10:05:41:932930] (tMain ) : Smdev: SMDEV initialization succeeded!

When run in ksh, gdb isn't put in background. Instead after quite a few lines of output from the image interspersed with gdb output lines "[New LWP ]", ksh seems to hang. Top then shows that both gdb and ksh are both running at approximately 50% CPU. But when I run the program in emacs or ddd, I don't have any problems. Since this always happens while gdb is trying to print more than 200 times "[New LWP ]", maybe we have a problem with both gdb and the image printing at the same time. I'd appreciate any help.
