I've replicated the problem with FC6
Apr 15 12:36:14 Updated: libX11.x86_64 1.0.3-7.fc6
Apr 15 12:36:16 Updated: libX11.i386 1.0.3-7.fc6
Apr 15 12:36:21 Updated: libX11-devel.x86_64 1.0.3-7.fc6
Temporary fix
rpm -e --nodeps libX11.i386
rpm -e --nodeps libX11.x86_64
rpm -i http://mirror.linux.duke.edu/pub/fedora/linux/core/updates/6 /x86_64/libX11-1.0.3-6.fc6.x86_64.rpm
rpm -i http://mirror.linux.duke.edu/pub/fedora/linux/core/updates/6 /x86_64/libX11-1.0.3-6.fc6.i386.rpm
-- Restart your X server --
This problem seems to be affecting some other Fedora packages as well,
however, on such occasions it appears that libX11 has been misused.
To diagnose the problem I installed
http://mirror.linux.duke.edu/pub/fedora/linux/core/updates/6 /x86_64/debug/libX11-debuginfo-1.0.3-7.fc6.x86_64.rpm
I then ran IDL in debug mode
D_LIBRARY_PATH=/usr/local/rsi/idl_6.3/bin/bin.linux.x86_64/ gdb /usr/
local/rsi/idl_6.3/bin/bin.linux.x86_64/idl
I set a break for XPutImage. I was hoping to see something similar to
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=236006 but I
don't
rbreak XPutImage
run
This starts IDL
IDL> tvscl, dist(500)
% Compiled module: DIST.
