            Bug ID: 31084
           Summary: -break-condition compare strings
           Product: gdb
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mi
          Assignee: unassigned at sourceware dot org
          Reporter: epasveer at att dot net
  Target Milestone: ---

What is the proper syntax to add a condition to a breakpoint to break if a
string matches a text.  Same question to -break-insert.


gdb) 
-break-condition 1 name.c_str() == "ernie"
^error,msg="No symbol \"ernie\" in current context."
(gdb) 
-break-condition 1 $_streq(name.c_str(), "ernie")
^error,msg="Problem parsing arguments: break-condition 1 $_streq(name.c_str(),
\"ernie\")"
(gdb) 






$ more gdbmi_condition.cpp 
#include <iostream>
#include <string>

int main (int argc, char* argv[]) {

    std::string name = "";

    name = "ernie";

    // Create the breakpoint with a string condition.
    //
    // -break-insert -c 'name.c_str() == "ernie"' gdbmi_condition.cpp:16       
     // Failed parsing.
    // -break-insert -c '$_streq(name.c_str(), "ernie")' gdbmi_condition.cpp:16
     // Failed parsing.
    // -break-insert -c 'strcmp("xxxxx", name.c_str() == 0'
gdbmi_condition.cpp:16   // Is accepted but breaks eventhough strings are
different.

    std::cout << "Name is: " << name << std::endl;

    return 0;
}

I think it should work if you quote the whole condition, like this:

-break-condition 1 "$_streq(name.c_str(), \"ernie\")"

Sweet!  Yes, indeed.  It does work after all the escape'isms.

I can implement this in my Seergdb debugger.

Thanks for your quick help.
