Why does everyone seem to think this is a Java bug?
My system generated crash report (including a core dump) that identified a segfault
in the Java runtime. A Java process is started by JGR(). JavaGD() seems to start
another Java process
The OP's log starts with segfaults (signal 11) in a Java process:
Sep 9 08:51:12 localhost audit[53948]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=2 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=53948 comm="Thread-5" exe="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.265.b01-1.fc32.x86_64/jre/bin/java" sig=11 res=1

The system log
showed that a crash occurred in Rf_eval (libR.so + 0x157ab3); i.e., in
the R library. The stack trace shows a lot of calls to these
functions:
bcEval
forcePromise
getvar
R_execClosure
Rf_appyClosure
Rf_eval
It's possible that R is being handed an _expression_ to evaluate that is
so complex that it runs out of stack space, or there could be an
infinite recursion bug in R somewhere. If the former, the solution is
to bump up the stack space. I would try the -Xss argument to java
first to see if that makes the issue go away. I'm not sure what the
default value is, so I don't know what to suggest, but maybe start
with something like -Xss4M. If that fixes the issue, then retry with
successively smaller values to find something reasonable that is still
big enough to work.
The problem seems to be specific to Fedora 32.
