EV 4.36 makes perl dump core

[Thomas Klausner]

Hi!

I've tried updating EV in pkgsrc from 4.34 to 4.36, but I see core
dumps when running the tests.

I then did the update to 4.35, which works fine. So the problem is in
the change from 4.35 to 4.36.

4.35:

t/00_load.t ........ ok
t/01_timer.t ....... ok
t/02_once.t ........ ok
t/03_keepalive.t ... ok
t/04_stat.t ........ ok
t/05_priority.t .... ok
t/06_loop_once.t ... ok
t/07_loop_timer.t .. ok
t/08_async.t ....... ok
t/09_brandon.t ..... ok
t/11_signal.t ...... ok
All tests successful.
Files=11, Tests=6875,  6 wallclock secs ( 0.07 usr  0.03 sys +  0.07 cusr  0.01 csys =  0.18 CPU)
Result: PASS

4.36:

There are already warnings in the 4.36 build that do not appear in the 4.35 one:

and many more similar ones, with increasing line numbers.

mv EV.xsc EV.c

When I revert the typemap changes, it builds and runs fine.  (Ok,
there are no real other changes, so that is not unexpected...)  I
tried fiddling with it for a bit but didn't find the subset to revert
to fix this.

The environment is NetBSD 11.99.2/x86_64 in case it matters.

Anyone else seeing this? Any hints on a solution?

Thanks,
 Thomas
