PIR_WARMUP=3 fails test_release_1

[fikovnik]

While playing with the kill-time-based-heuristics, I set PIR_WARMUP=3 to see how it affects the benchmarks. When the pipeline was running there was a failure:

/bin/bash: line 1:  6173 Segmentation fault      (core dumped) LANGUAGE=en LC_ALL=C SRCDIR=. R_DEFAULT_PACKAGES= ../bin/R --vanilla < reg-tests-2.R > reg-tests-2.Rout.fail 2>&1
running code in 'reg-tests-2.R' ...make[2]: *** [Makefile.common:109: reg-tests-2.Rout] Error 1

Looking further, in the log file:

Traceback:

An irrecoverable exception occurred. R is aborting now ...

I tried to reproduce it locally on prl5, but with no success. Simply running:

build-release$ RIR_CHECK_PIR_TYPES=1 bin/gnur-make-tests check-devel

did not trigger it again.
