Re^2: memory leak when using tail recursion?

ikegami,
What version of perl? I ask because I see the memory leak locally with perl -v

This is perl, v5.8.8 built for MSWin32-x86-multi-thread
(with 25 registered patches, see perl -V for more detail)

The exact same build. The memory usage does go up for each recursive call to `bar` (which is why I had to lower the max value for `$i`), but it does get reclaimed.	[reply] [d/l] [select]

ikegami, Very interesting. I am up over 200MB in 30 seconds if I use the block form of if. If I use the post modifier form of if, it stays fixed at 2MB. Cheers - L~R	[reply]

The `if` statememt creates a stack frame, while the statement modifiers do not. `goto` must reuse the sub's frame when possible. It apparently can't when the sub's frame isn't the topmost frame on the stack.	[reply] [d/l] [select]
