[Pkg-octave-devel] Bug#699300: octave matrix multiply grief

[William Ludescher <whludescher@verizon.net>]

Rafael,
	Apologies for my ham-handed carelessness both on my test and email cc.
I will attempt to reform. Well I retyped your test and here are the
results:

What I typed: echo 'a=[1 2; 3 4]; b=[5 6;7 8]; a*b' | strace octave

Relevant strace output: 

mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb77a5000
read(0, "a=[1 2; 3 4]; b=[5 6;7 8]; a*b\n", 4096) = 31
time(NULL)                              = 1359724093
--- SIGILL (Illegal instruction) @ 0 (0) ---
futex(0xb5d1e8c0, FUTEX_WAKE_PRIVATE, 2147483647) = 0
write(2, "panic: ", 7panic: )                  = 7
write(2, "Illegal instruction", 19Illegal instruction)     = 19
write(2, " -- stopping myself...\n", 23 -- stopping myself...
) = 23
write(2, "attempting to save variables to "..., 49attempting to save
variables to `octave-core'...
) = 49
open("octave-core", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 3
write(2, "save to `octave-core' complete\n", 31save to `octave-core'

) = 31
write(3, "Octave-1-L\0\10\0\0\0.nargin.\0\0\0\0\0\377\6\0\0"..., 244) =
244
close(3)                                = 0
rt_sigaction(SIGILL, {SIG_DFL, [], SA_RESTART}, {0xb6ff61e0, [],
SA_RESTART}, 8) = 0
tgkill(2678, 2678, SIGILL)              = 0
sigreturn()                             = ? (mask now [])

Illegal instruction


I presume that the \n came from the echo command. However, why does
octave think that this is an illegal instruction?
