| Signal 12 on simple ldd / Linux |

Hi,
FreeBSD 5.3-RELEASE-p10 (Yea, I know, there are reasons)
/proc and /linprocfs are mounted onto a point under an NFS
mount point
(This shouldn't matter since the fs is local still, no?)
When trying to ldd a binary, I get a signal 12. When I
truss
it, the last bits I get are :
82825:

On a working system, I get :

linux_open("/lib/libgcc_s.so.1",0x0,027757762100)

19038: linux_mmap(0xbfbfe82c) = 675119104

19038: mprotect(0x28153000,4096,(0x1)PROT_READ) = 0

19038: munmap(0x28155000,0x2c9b) = 0

(0x0)^M
19038: linux_getpid() = 19038
(0x4a5e)^M
(etc)
Was it the "#243" that killed it, or
"linux_modify_ldt"?
Thanks, Tuc

syscall 243 is set_thread_area.. TLS stuff. It was
implemented in 7-current.
