[Qemu-devel] [PATCH 3/3] build-sys: enable sanitizers by default with --enable-debug

[Marc-André Lureau]

The original commit 247724cb302af5d70c8853154b640dfabf2bbb56 was meant
to enable sanitizers by default when --enable-debug, but failed
because of a gcc static linking bug. Try to enable it back now that
there is a stronger check.
