Wrong handling of string([]byte) ? #4072
Description
I have a variable which is []byte:
(dlv) p p.output
[]uint8 len: 26, cap: 16384, [116,121,112,101,...+22 more]
I want to see it as a string:
(dlv) p string(p.output)
"type T struct {\f\f\t�fldcom�...+-4 more"
First - why so short? I have max-array-values = 4 and max-string-len = 256. This is neither of those.
Second: What does +-4 mean - At first I thought it was just 4, but:
(dlv) p string(p.output[8:])
"truct {\f\f\t�fldcom�...+-4 more"
??? I can only guess those mystery characters are screwing something up? Here's raw data:
(dlv) p p.output[0:26]
[]uint8 len: 26, cap: 16384, [116,121,112,101,32,84,32,115,116,114,117,99,116,32,123,12,12,9,255,102,108,100,99,111,109,255]
