Octave-2.1.50 startup segfault on ARM (SA1110)

[Simon Pickering]

Hello All,

I thought it was about time to try cross-compiling 2.1.50 (I did 2.0.17
when it came out and it works fine on my Zaurus sl5500). I get a SEGSIGV
as soon as I start the binary. I did a search of the mailing lists but
didn't come up with anything in particular other than making sure that
your libc headers were correct for the lib you're using. They are. I
wonder whether anyone on the list could give me some suggestions?

I used a GCC 2.95.3 ARM cross-compiler on an i686 Mandrake 9.1 box. I
didn't sent it with this email as it's quite long but I have the
config.log file handy if it contains something which may be of help.

I am running (or rather trying to run) Octave on a Sharp Zaurus Sl5500
(SA1110 processor, 64MB RAM) with an OZ3.3.5 ROM (for those who care
;-). This is what I get on my Zaurus (it runs as root by default BTW):

# ./octave-2.1.50
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
SIGSEGV
#

Dmesg shows nothing of interest (I don't know whether it ought to).

Strace shows the following (just the end part):

brk(0x314b000)                          = 0x314b000

bastring.h does exist, and there's no #include etc. on the line to which
it refers. Any ideas?

Thanks,
