[Bas Couwenberg]

What are the versions of the installed grass & libgdal-grass packages?

[Bas Couwenberg]

It's specific to the Ubuntu builds, the packages from Debian experimental don't have this issue:

Is PIE disabled for all three related packages (grass, gdal & libgdal-grass)?

It's likely that the PIE option for libgdal-grass was not disabled for the Ubuntu build causing this issue.

The buildlog confirms this:

g++ -Wall -fPIC [...] -fPIE -fstack-protector-strong -Wformat -Werror=format-security  -c -o ogrgrassdriver.o ogrgrassdriver.cpp

Add the following to debian/rules for libgdal-grass:

# Disable PIE on Ubuntu where it's still problematic
VENDOR_DERIVES_FROM_UBUNTU ?= $(shell dpkg-vendor --derives-from Ubuntu && echo yes)

ifeq ($(VENDOR_DERIVES_FROM_UBUNTU),yes)
        export DEB_BUILD_MAINT_OPTIONS=hardening=+all,-pie
endif

Or get the updated source from git:

Thanks Bas, the patch has been applied both to our ppa and ubuntugis-experimental
