Android :: Build Library Without Optimization In Order To Properly Debug It

I'm trying to debug native library (in particular, libril.so). Everythig is going fine, breakpoint is being hit, I can go thru the lines of RIL_onRequestComplete() function. But when I tried to print out particular struct I got,

(gdb) print pRI $2 = <value optimized out> (gdb) print pRI->pCI $3 = (android::._115 *) 0x613 (gdb) print pRI->pCI->requestNumber Cannot access memory at address 0x613

I suspect it could be due to optimization done by compiler. But when I tried to add,

LOCAL_CFLAGS := -g3 -O0

into makefile of the lib, I've got another problem when I cannot correctly set breakpoint on desired function. Instead of correct one,

(gdb) break RIL_onRequestComplete Breakpoint 1 at 0xae402e4e: file hardware/ril/libril/ril.cpp, line 1800.

I got,

(gdb) break RIL_onRequestComplete Breakpoint 1 at 0xffffab44: file bionic/libm/src/s_tanf.c, line 42.

Does anybody know what could be a problem, and what is the right way to handle this?
