Hi all, We've met strange problem - g++ omits debug info for local symbols in one cpp file of our project but another files are compiled well. -O0 -g3/-gdwarf-2 are specified for all files. For the first glance there is no difference in the files content, just common C++ code without templates, etc. We checked generated .S file - it really lacks debug info for local symbols. Methods formal parameters are present. Google search did not help. Which gcc options may help us to solve this problem or to investigate it deepper? Thanks in advance Vladimir Simonov
