I was specifically using "require" since it is runtime. Whether it is actually required depends on configuration. The input or output files may be fixed-width, and I didn't want to load Text::CSV_XS unless it was actually needed. I also didn't want to have modules loaded in more threads than needed, although I couldn't avoid having threads created by the input thread inheriting it if the input file is delimited.

I figured it had to do with garbage collection, because in my actual script, it would only happen on the last chunk of queued data, so I figured after the input file was closed and no longer referenced. I began suspecting it was related to Text::CSV_XS because it only happened with delimited files when that module was used.

I hadn't known that modifying the GST in a thread was bad. Is that documented? I thought everything global for a thread was essentially copied from the parent, and I was trying to minimize what would be copied.

I appreciate your help! I was hoping to confirm that requiring the module globally before creating threads would eliminate the issue, since I can't have intermittent crashes in production. I wouldn't want to sacrifice performance by using Text::CSV_PP instead, though. I created a bug report.
