Hi,
Yes i am working with fontconfig-2.6.0 stable release .
I tried debugging fontconfig for the issue & found that application gets stuck at FT_Load_Glyph. Below is some backtrace of gdb where the application gtk-demo gets stuck.

Any guidance where should i look in font config code to debug / solve the issue.
