Good catch guys. This is indeed a bug. You can actually reproduce it
using just a simple string array:

pro cr56738_write
a = bytarr(100000)
openw,lun,'c:/test.dat',/get_lun
writeu,lun,a
free_lun,lun
end

pro cr56738_read
openr,lun,'c:/test.dat',/get_lun
out = replicate(' ', 100000)
readu,lun,out
free_lun,lun
end

cr56738_read & print,(memory())[3]
3005089
cr56738_read & print,(memory())[3]
4005080
cr56738_read & print,(memory())[3]
5005080

This has been logged as CR56738, and will be fixed in the next IDL
release.

As a workaround, you could read the data as bytes, and then convert
the result to a string afterwards.

Cheers,
