WebThe option --merge-recursive-frames= instructs Valgrind to detect and merge recursive call cycles having a size of up to frames. When such a cycle is detected, Valgrind records the cycle in the stack trace as a unique program counter. The value 0 (the default) causes no recursive call merging. WebMany recent compilers allow you to build an optimized application with debug information present at the same time. For example, typical options for GCC are: -g -O2.
