Please look at the core file with readelf -n. Then compare the note sizes to what the <sys/procfs.h> types say. Perhaps the gdb build and hurd builds are out of synch.
Here is the output of readelf on a forced coredump (with gcore) on sleep. The sizes for each note section look ok, but it looks like that the utsname note isn't recognized. /home/ams $ readelf -n core.10879 Notes at offset 0x00001000 with length 0x0000190c: Owner Data size Description CORE 0x00001400 Unknown note type: (0x0000000f) CORE 0x000000c4 NT_PSINFO (psinfo structure) CORE 0x00000038 NT_PSTATUS (pstatus structure) CORE 0x000001e0 NT_LWPSTATUS (lwpstatus_t structure) CORE 0x000001e0 NT_LWPSTATUS (lwpstatus_t structure) _______________________________________________ Bug-hurd mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-hurd
