Bug #3557
closed
Marshal.dump fails for large Arrays of Arrays
Description
=begin
def test
n1 = 10
n2 = 34000
b = Array.new n1
for i in 0 ... n1 do
a = Array.new n2
for j in 0 ... n2 do a[j] = j end
b[i] = a
end
Marshal.dump b
end
dump_arg_data in marshal.c gets prematurely freed by GC run_final()
Enclosing the Marshal.dump with GC.disable and GC.enable fixes the problem

2010-05-31 sounds truly old.
I can't reproduce it with the recent.
$ ./ruby -ve 'p Marshal.dump(Array.new(10){[*34000.times]}).size'
ruby 1.9.2dev (2010-07-11 revision 28610) [i386-mswin32_80]

I suspect it has been fixed at r28467.

I can't reproduce it either, using rc1

Notice I am running x64 on mswin64 (xp64 sp2), not i386 on mswin32 or mingw32.
My version passes "nmake test".

Thank you!

Many other combinations of Array lengths that previously failed work properly now!
Sorry, I missed 1.9.2-rc2 until you pointed it out.
