I think the short answer is "no". :-(
I'm trying to remember what all I did when I was working on
updating the linux emulation to support flashplayer 11.
I recall that there was no one thing that was the best way
to figure out what was going on, I used a variety of techniques.
enabling TRAP_SIGDEBUG in amd64/trap.c was helpful.
I think I used the kernel debugger to examine user process
memory too... maybe by setting a breakpoint on coredump()? not sure.
I think I did use netbsd's gdb at times, and it was sometimes
helpful even though it didn't recognize the linux executable format.
I spent a little time trying to make linux gdb work
but gave up before I got it working.
alas, I'm not remembering a lot of details,
I think I blocked out the memory because it was so painful.
also, probably most of what I'm remembering is from making
the ltp test suite work rather than flashplayer itself.
if you send me a pkg tarball of flashplayer 24,
I'll try to fix the emulation.

if the distfile is gone, is there any point in keeping it?
