Invalid escape sequence

[gil-n]

hi,

I'm getting an MI parse error: message:"Invalid escape sequence" when calling: evalExpression("(ptr->data)" )

GDB return the following string: "17^done,value="0x5d2310 '\253' <repeats 16 times>"
The problem is that string contains invalid js escape sequence with \253 which causing the MI parser to fail.

A possible fix: modify GDB.prototype._line_output_handler function by adding:
line = line.replace('\'', '\\')

Thanks,
Gil

Hi Gil

What version of GDB are you testing with? GDB should send out escaped strings.
This is what I get here:

5-data-evaluate-expression --thread 1 --frame 0 teststr
5^done,value="0x400574 '\\253' <repeats 16 times>"
(gdb)

I'm using: GNU gdb (GDB) 7.10.1
This is the line value: 36^done,value="0x7a22d0 '\253' <repeats 16 times>"

The code runs on windows, i can also test on linux and let you know.
Now i use the code: line = line.replace(/\\(\d)/, '\\\\$1')
