Description

I don't have any PPC machines, so this bug is probably going to sit here doing nothing. That said, you might try: * Running the core through gdb and seeing if anything obvious happens there. * Filing a bug with the R upstream (including the core and/or backtrace) Created attachment 934322 [details]
ok-errors.Rout.fail
I did a mock build on a ppc64 guest and failed the same way as above.
I found the following "ok-errors.Rout.fail" file in the tests/ subdir.
as per its comment seems the tests voluntarily tried the limits.
next attachment with gdb

R_gdb_core_backtrace.log
the attached R_gdb_core_backtrace.log show that core is a concequence of the infinit loop in eval.c that is detected but seems not handled properly.

tracked upstream by https://bugs.r-project.org/bugzilla/show_bug.cgi?id=15963 (In reply to Tom "spot" Callaway from comment #1) > I don't have any PPC machines, so this bug is probably going to sit here > doing nothing. That said, you might try: Tom, we do have ppc64 systems for that. Please ask on #fedora-ppc or send me your public ssh key. []'s Gustavo The issue is related to the stack being too small when running the ok-errors.R test case. This test will cause an infinite recursion loop, which should be interrupted by R. On x86_64, this works as expected. On ppc64, the stack size needs to be doubled to 16384 (ulimit -s 16384) to be able to run successfully, otherwise the segfault will happen. I'm currently testing ppc64 builds with modifying the ulimit before running 'make check' in the .spec file. Created attachment 938242 [details]
