The -analyzer-display-progress displayed the function name of the currently analyzed function.
It differs in C and C++. In C++, it prints the argument types as well in a comma-separated list.
While in C, only the function name is displayed, without the brackets.
C++: foo(), foo(int, float)
In crash traces, the analyzer dumps the location contexts, but the string is not enough for -analyze-function in C++ mode.
This patch addresses the issue by dumping the proper function names even in stack traces.
