$ ./perl -ILib -e 'use XSLoader; warn $$; eval { XSLoader​::load() } while 1'

Run that script and watch the memory usage go up. I found this with Porting/leakfinder.pl\, so it is an SV leak.

1. I suspect that the 'L' in the second term should be lower-case\, i.e.​:

./perl -Ilib -e 'use XSLoader; warn $$; eval { XSLoader​::load() } while 1'

2. What is a good way to "watch the memory usage go up"?

Yes. I often make that typo\, but it makes no difference on a case-tolerant file system.

I use top.
