Description of problem:
pango installed from the F22 "updates" repo contains a critical bug that causes
a buffer overrun on 64-bit architectures when rendering a glyph into a
FT_Bitmap that is too small.
When pango 1.36.8 is built from source on the same system, no buffer overrun is
observed (using valgrind).
Version-Release number of selected component (if applicable):
pango-1.36.8-5.fc22.x86_64
How reproducible:
Always.
Steps to Reproduce:
See http://quality.runrev.com/show_bug.cgi?id=15581 for detailed instructions
for reproducing, plus logs.
