Description James Bottomley 2001-01-04 21:52:43 UTC
When you execute ksh, it gives:

ksh(26747): unaligned access to 0x600000000000d5e8, ip=0x20000000000a92d0
Bus error (core dumped)

This can be fixed by making the default allocation alignment 16 bytes on
ia64 platform with the following patch:

Thanks for the patch, will take a look at it soonish.

Verified, applied and upstreamed - look for pdksh-5.2.14-10
