Trying to parse for example the following result results in a buffer underflow of lengthIndex.
{"jsonrpc":"2.0","id":0,"result":"0x0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000005468747470733a2f2f7261772e67697468756275736572636f6e74656e742e636f6d2f6c6f72626b652f426c6f636b426f6172642f6d61696e2f6173736574732f64656661756c745f68617264776172652e676966000000000000000000000000"}
while (lengthIndex > 0) { Serial.println(index); asciiHex += v->at(index++); lengthIndex -= 32; }
checking if lengthIndex is smaller than 32 before subtracting or changing lengthIndex to a signed int fixes the segfault
Thanks @Bluegales I'll take a look
