[geomview-users] SaVi segfaulting when writing to a geomview pipe?

[Lloyd W. <llo...@ya...>]

I'm dealing with the odd situation on linux where
geomview -run savi
works just fine if geomview and savi are installed as
ubuntu packages, but if I compile savi 1.5.1 (matching
the package) SaVi segfaults on first attempting to write to the
pipe to geomview via fprintf.


stdout is set up to point to geomview and dup'd, and there's
a lot of error checking in that code to test for failures
during setup. Those checks pass, but as soon as you fprintf
to the pipe - boom, goodbye your compiled savi.


This code hasn't changed (ie I'm not smart enough to change
it) in years...

Has something changed in stdlib or in how file pointers

can be used and abused in gcc? Ideas to investigate  welcome.

thanks
