Package: libopenmpt0
Version: 0.2.7386~beta20.3-3+deb9u2
Severity: important
Dear Maintainer,
Using this shared library with external application creates segfault
with memcopy related functions.
This can be avoided if one would recompile with -O3 optimization as actually
does upstream in their makefile (not autotool sources)
Adding this to rules effectively fixes issue:
export DEB_CXXFLAGS_MAINT_APPEND = -O3
