[9fans] questions about trump and leak

[Axel Belinfante]

Triggered by Russ' mention of trump I tried to have a look
at memory usage/leaks of a simple file server I'm playing
with ('working on').

Trump seems to indicate a free for each malloc I'm concerned about
(assuming I'm interpreting its output correctly).
Trump also gives some lines starting with ``0x00000000 free'' ;
do they mean that free gets passed a null pointer? Or?

Leak -b produces an image containing a red part.
However, leak -s gives me nothing (immediately a prompt).
This confuses me; what am I missing?

I updated yesterday evening, and just some minutes ago
made /sys/src/libc/port/pool.acid (leak complained it to be missing)

Thanks,
Axel.

Yes.

This is a bug in leak -b.
