Source: crash
Severity: serious
Tags: upstream patch ftbfs
Justification: fails to build from source (but built successfully in the past)
Dear Maintainer,
The crash package sometimes fails to build when dpkg-buildpackage is
invoked with -j > 1:
# dpkg-buildpackage -us -uc -j4
[...]

This is because crash's configure rewrites Makefile via a temporary file
(Makefile.new) and it is now getting invoked multiple times in parallel.
This is a problem upstream.
It can be avoided with the following change:
--- a/debian/rules
+++ b/debian/rules
@@ -12,8 +12,7 @@ include /usr/share/dpkg/buildflags.mk
dh $@
override_dh_auto_build:
- dh_auto_build
- $(MAKE) extensions lzo snappy
+ dh_auto_build -- all extensions lzo snappy
override_dh_auto_clean:
cp $(CURDIR)/Makefile $(CURDIR)/debian/Makefile.ori

Because the package uses debian/compat level 9, dh forces -j1.
