Thanks for the feedback.

There is a list in; section Known Versions.

I'm planning on releasing wisi and ada-mode thru Alire, which I hope
will reduce the compiler confusion. However, if people are using other
compilers, gpr_query must still be compiled for them.

In incremental mode, it should use a lot more; it saves the syntax tree
for each buffer you have open. The memory used for error
recovery is typically larger than a single syntax tree, but transient.

Did you try (setq wisi-incremental-parse-enable t)?

You can recover the memory used by one buffer with M-x
wisi-reset-parser. You can recover all the memory used by all the
buffers with wisi-kill-parser.

On Windows, the memory is returned to the OS; I'm not sure if that's
true on Linux.

What do you use for cross-reference?

See the new functions wisi-parse-enable-memory-report,
wisi-parse-memory-report-reset, wisi-parse-memory-report. Maybe you can
get some useful information.

If you suspect there is a memory leak, rather than just a lot of memory
for a lot of buffers, a recipe that reliably causes the memory report to
grow when it should not would be best.
