Josef/ Julian The problem I have with --demangle=no is that:
a) I am using Python to generate code dynamically and therefore, I don't know of a good way of mapping symbols to addresses in a post processing cycle. At every boot up cycle, the symbol name to address location appears to be vastly different. b) My device runs into either an out of memory situation or ends up in a SIGSEGV crash. As a result, no post processing method for recovering symbols comes to my mind. Given these circumstances, if you are aware of any clever method of recovering the symbols for dynamically generated code, please do let me know and I shall gladly implement your suggestion.

I have the exact same question as Julian here: what is your problem with "--demangle=no"? It does not cut down any functionality. Symbols will just show up demangled, which you can cope with in a postprocessing step afterwards. > Is there another way in valgrind to restrict the string size offered > to VG_(strcmp)() so that it won't crash?
