Native symbols are not present in backtrace

[gavv]

For some reason, when there is a crash in native code, the backtrace does not show symbols in frames in native codes. Neither in console output, nor in gdb when I open core dump.

I checked that both libroc_jni and libroc have debug symbols, that gdb has correct paths to these libs, and tried to force gdb to load symbols from them (using sharedlibrary command). It did not help.

Without this, it's very hard to debug crashes in native code.
