Hi,
I observed that IDL 6.4 x64 and 7.1 x64 (Windows 7 x64) crashes each
time I'd like to do the following:

IDL> test_histo_bug
% Compiled module: TEST_HISTO_BUG.
L INT = Array[5, 5]
L DOUBLE = Array[5, 5]
H LONG = Array[7]

IDL> test_histo_bug,/crashme
->IDL crashes completely

pro test_histo_bug,crashme=crashme
l=$
[[0,0,0,0,0],$
[0,1,1,1,1],$
[0,1,1,1,1],$
[0,1,1,1,1],$
[0,1,1,1,2]]
help,l
l=keyword_set(crashme)? ulong(l) : double(l)
h=histogram(l,reverse_indices=r,nbins=7,min=1)
help,l,h
end

Is it possible that HISTOGRAMM can't *handle* ULONG values? May be
someone can shed some light on this behaviour?

Thanks in advance
