<pre>ccache compiled code has *.i filenames instead of *.c file names so the
breakpoint can't be found.
FWIW, I don't know how it does it, but mingw/gdb can set breakpoints in ccache
compiled files just fine.
vharron-macbookpro:bp vharron$ cat bp.c
#include <stdio.h>
int
main() {
printf("Hello, World!\n");
return 0;
}
working case:
vharron-macbookpro:bp vharron$ gcc -c -o bp.o bp.c
vharron-macbookpro:bp vharron$ gcc -o bp bp.o
vharron-macbookpro:bp vharron$ lldb bp
