OOM for record followed by other character. #15243
Description
Describe the bug
There is a memory leak/unterminated loop on the current main branch, but not in the released 0.102.0
Bisected down to #15023
How to reproduce
Will run out of memory
{a:b}/will not run out of memory
{}/For testing on Linux you can set the ulimit in a bash session to not wait for ever or having to manually kill
#!/usr/bin/env bash
# build untouched from the memory limit
cargo build
# 1 GB of virtual mem
ulimit -v 1024000
target/debug/nu -c "{a:b}/"Expected behavior
Not going out of memory, still covering the spread operator edge cases from #15023
