Package: mini-buildd
Version: 1.0.0~rc.1
Severity: normal
I'm not really sure if this is a bug in mini-buildd, or in
libeatmydata, or in OpenCV. But I first encountered the problem in
mini-buildd, so I'm starting here. It's also likely related to
#702711.
I have a package that links against opencv_highgui and also uses
help2man. This causes a FTBFS from within mini-buildd, because:
$ echo "int main () { }" > test.c; cc -g -o test test.c -lopencv_highgui
$ LD_PRELOAD=/usr/lib/libeatmydata/libeatmydata.so ./test
Fatal: can't open /dev/urandom: Bad address
Aborted

This is easy to track to code in libeatmydata that returns EFAULT if
open() is called before the constructor for libeatmydata is called.
I'd argue that either:
- libeatmydata should be fixed so that it "always" works
- or libeatmydata should be off by default in mini-buildd generated builders
