[parisc-linux] Troubles with expect scripts

Hi all,

	We are using some scripts using Expect language and they die with a
segmentation fault and you can read this output in the dmesg:

do_page_fault() pid=1068 command='webco' type=15 address=0x000ac800
vm_start = 0x00020000, vm_end = 0x00021000

I have recently updated glibc 2.2.4-3 but I tried Helge Deller's
"working" version with no result and I tried to recompile the package
and it was useless :( I also attached the output of strace -o output
webco 

If anyone has an idea, please try to fix it.

This isn't a fix, but may be a workaround:  Try "export LD_BIND_NOW=1" to
disable lazy binding by the dynamic linker.
