This has been rejected upstream as a bug. For now, I suggest to not use malloc_usable_size.I'll followup upstream.

MALLOC_CHECK_=1 works as well of course, and prints the warning:

Workaround: run sublimetext with MALLOC_CHECK_=0

The Open Build Service provides a platform to build for all RPM/Deb distros from one set of .spec and debian/* files.

Seeing the same here. The openSUSE Build Service checkouts projects separating namespaces with colons:

osc co home:dmacvicar

cd home:dmacvicar

// modify package

EDITOR=sublime_text osc ci
