#210 Incorrect handling of debuginfo files with debug data only


For certain libraries (notably, libc), some distros (recent Fedora and RHEL, for example) put only the debug info sections into *.debug files; the basic symbol info (.symtab/.strtab) is retained in these specially stripped libraries. The repercussions of that technique is that when oprofile is processing a debuginfo file in bfd_support.cpp:get_symbols(), the call to bfd_get_symtab_upper_bound returns 0 for nr_syms since there is no symbol info in the debuginfo file (only debug info). And since nr_syms is less than '1', we simply return.

    This bug has been fixed. See posting to the oprofile-list on Feb 29, 2012, subject heading "Re: [PATCH] Fix debuginfo processing to handle no symbol info in debuginfo file".
