rr segfaults when recording an execution

I am trying to record a program's execution using rr and it looks like rr is encountering a segmentation fault. The command to record execution is something like rr record -n <program> <arguments>. Aside from rr: Saving execution to trace directory <trace_output_dir>., there doesn't seem to be anything useful output to the terminal(all other output are logs from the program). As suggested in rr chatroom, I tried setting log level using RR_LOG(something like RR_LOG=warn rr record -n <program> <arguments>) but there was no useful output. I even tried setting log level to debug but nothing.

Since there was no useful log output, I attached gdb to rr and got the following traceback:

#0  0x00007f92b0df455b in kill () at ../sysdeps/unix/syscall-template.S:78
#1  0x00000000005134ac in rr::RecordCommand::run(std::vector<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >&) ()
#2  0x0000000000498163 in main ()
#3  0x00007f92b0dd50b3 in __libc_start_main (main=0x497e10 <main>, argc=0x7, argv=0x7fffc2c759e8, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>,
    stack_end=0x7fffc2c759d8) at ../csu/libc-start.c:308
#4  0x0000000000498579 in _start ()

Unfortunately, I cannot build and run a debug build of rr: some of rr's build dependencies conflicts with other essential packages on my system. I did not find an installable debug build of rr online: if there is one, I can try running that. I am using rr 5.4.0 on Ubuntu 20.04.2 LTS with Linux kernel 5.8.0-59. If any other information would be useful, I can provide that.

The report names rr::RecordCommand::run in the traceback but provides no reproducible program or source file. Start by reproducing rr record -n on Ubuntu 20.04.2 with Linux 5.8 and rr 5.4.0, then inspect that entry point under a debug build. Done means identifying why recording reaches kill() and documenting or fixing it with a reproducible test.
