Floating-point exception in pixman's combine_inner function triggered only
via the stress-test developer test binary, not the runtime library.
The vulnerable code is in stress-test.c which is never compiled, shipped,
or installed in the libpixman-1-0 package present in Echo containers.
Debian marks this as "unimportant" with note "Crash in test tool, no security impact."
No upstream fix after 2.5+ years.
