It appears that in the latest version of libXm.4.0.4 on Trusty (14.04), on certain types of X events, it causes a segfault. I've isolated this to a particular version of the library and OS rev. Our application works fine for OS older than 14.04, ie 12.04 etc. I also confirmed the version issue by copying libXm.4.0.3 from a 12.04 machine onto a 14.04 machine and it allows the program to work normally. I basically copied libXm.4.0.3 from a 12.04 machine to the 14.04 machine and created a symlink to it: ln -s /usr/lib/x86_64-linux-gnu/libXm.4.0.3 /usr/lib/x86_64-linux-gnu/libXm.4.0.4 So, whatever has changed between 4.0.3 and 4.0.4 has broken some API calls. It's hard for us to debug this from the application side b/c it generates a segfault, which causes the application to crash. Example of what causes the crash. When our application generates a child window which has text field widgets like a text field or textarea, typing into the field causes this crash. Any ideas on why the new version would cause these crashes? Looking at the release notes (/usr/share/doc/libmotif-dev/RELNOTES.gz), I see there were a number of bug fixes. Is it possible one of these fixes caused another bug? Thanks in advance.
