[Reproducible-builds] Bug#783130: r-base: FTBFS when setting TZ environmental variable

[Philip Rinn]

Package: r-base
Version: 3.2.0-2
Severity: serious
Tags: upstream
Justification: fails to build from source (but built successfully in the past)

Hi Dirk,

I was trying to understand why GNU R FTBFS in the reproducible build env[1]
while building fine on the buildds.
It turns out that setting the TZ environmental variable[2] crashes the build.

*** stack smashing detected ***: /tmp/buildd/r-base-3.2.0/bin/exec/R terminated

.... for a BT see [1] ...

The offending command is:

echo
"tools:::sysdata2LazyLoadDB(\"./R/sysdata.rda\",\"../../../library/tools/R\")"
| R_DEFAULT_PACKAGES=NULL LC_ALL=C ../../../bin/R --vanilla --slave



To reproduce:

I followed the steps in
https://wiki.debian.org/ReproducibleBuilds/ExperimentalToolchain#Usage_example

and used the rebuild.sh from
http://anonscm.debian.org/cgit/reproducible/misc.git/tree/prebuilder

But I guess just using

sudo TZ="/usr/share/zoneinfo/Etc/GMT+12" pbuilder ...

should also do the trick.

I don't have a clue why this happens - probably something for upstream?


Best,
Philip
