c++ - gdb corefile not see function parameters -


my application crashed due uncaught exception (my c++ code throws uncaught exception under condition). trying gdb corefile. binary library "not striped". , stack trace shows function (my code) uncaught exception thrown, when try print function arguments, "no symbol xxx in current context". info args return "no symbol table info available".

can shed light why ? due uncaught exception unwind/corrupts stack ?

thanks, frank

your binary lacks debug info.

if built gcc, , want debug core have (if e.g. it's hard reproduce crash), may able recover rebuilding binary exactly same source , command lines, adding -g compile , link commands. (note: must use same compile lines; replacing -o2 -g wouldn't do.)

if crash not hard reproduce, rebuild binary -g -o0, run under gdb, , enjoy "easy" debugging.

the binary library "not striped".

this doesn't mean think means. not stripped means symbol table still present in binary.

gdb read symbol table, , use map ranges of addresses function names.

but recover names , values of local variables , parameters, must compile debug info (which -g flag compilers).

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
