I've been running this now for three days on hiauly6 with a 32-bit 2.6.8.1-pa7 kernel (default c3000 config) doing almost continuous gcc builds. Things seem pretty promising. No random SIGSEGVs and expect seems to be behaving itself. > I had another SIGSEGV on gsyprf11. It looks as if this was in /bin/sh > although gdb doesn't say which program the fault ocurred in. This is definitely not the case with the 64-bit SMP kernel on gsyprf11. There I've been testing with an unpatched kernel. Expect works better with tcl8.3 but there are still some tests that fail when they shouldn't, and the output with tests which produce a large amount of output gets truncated. With tcl8.4, expect has major problems. The Tcl_Finalize patch doesn't fix them. I think we need to try Carlos's patch on a 64-bit SMP system to see if it helps the expect and SEGV problems. I'm off to Korea early Thursday morning so I can't do much more on this until I'm back in a couple of weeks. Dave -- J.
