Ubuntu 22.04下Gdb调试依赖C++的R代码触发段错误

问题描述 #

此前在Ubuntu 18.04下可正常使用gdb调试依赖C++源码的R代码，但升级到Ubuntu 22.04后，执行命令R -d gdb直接触发段错误（Segmentation fault）。单独运行gdb无异常，已尝试卸载并重装gdb，问题依旧。

排查操作及输出 #

为定位问题，执行了以下命令：

gdb -ex 'set env LD_LIBRARY_PATH /usr/lib/R/lib:/usr/lib/x86_64-linux-gnu:/usr/lib/jvm/default-java/lib/server' \
  -ex "set height 0" -ex run -ex where \
  -ex "info shared" --args \
gdb /usr/lib/R/bin/exec/R

得到的输出结果如下：

/u/sw/pkgs/toolchains/gcc-glibc/9/base/share/gdb/python/gdb/command/prompt.py:48: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if self.value is not '':
