Your while-loop reads line by line, so you can never match the previous line in a regex.

I gets much easier if you read the whole file into a string, and then apply a substitution.

I don't know what output you expect, but this might do you want: 

s/^\s*start_of_block\s*\{.*?\};\s*//xmsg;

If not, please tell us exactly what output you want.
