I keep a list of testcases which I see that have such behaviour: * gdb.base/annota1.exp * gdb.base/annota2.exp * gdb.base/annota3.exp * gdb.base/checkpoint.exp * gdb.base/display.exp (observed in GDB 6.5, seems fine in 6.6) * gdb.base/interrupt.exp (observed in GDB 6.5, seems fine in 6.6) * gdb.base/multi-forks.exp * gdb.threads/attachstop.exp (observed in GDB 6.5). Test dies with: ERROR: couldn't open "/proc/28696/status": no such file or directory * gdb.threads/schedlock.exp * gdb.threads/watchthreads2.exp Is it useful to have such list on the wiki? -- []'s Thiago Jung Bauermann Software Engineer IBM Linux Technology Center
