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
