Re: [Linux-abi-devel] mmap() Related Bus Error?

[Bryan E. <ell...@jc...>]

Thanks for the assistance in response to my last post. I believe I may
have made some headway, though the application is still not running.
I followed Christoph's advice and tried using the libc from the
/OpenServer directory on a UnixWare 7 box. As you can see from the
information below, at least the trace is alot shorter :)

It seems that munmap is returning an EINVAL (Invalid Argument). I
checked through the abi source and only found reference (in my
circumstance) to munmap in the sco/sysent.c file. Could this problem be
related the sco syscall map?

Any further advice anyone can give on this problem would be greatly
appreciated. Trace and other related information follows.
