Hello Andrey,
I tried different options to have symbols for gdb, your suggestion and others with CFLAGS ( -g, -ggdb) but any seems the right.
> Try 'configure --disable-optimizations'.
Note: After quit gdb the fio load agaisnt CPU come back.
I tried :
# ./configure --disable-optimizations
# gmake CC=gcc
I have with gdb the same output:
