Fix build failure in symfile.c::unmap_overlay_command (GCC5 bug)
Compilation of (GDB) 7.9.50.20150127-cvs with (GCC) 5.0.0 20150127 fails with In file included from symfile.c:32:0: symfile.c: In function 'unmap_overlay_command': objfiles.h:628:3: error: 'sec' may be used uninitialized in this function [-Werror=maybe-uninitialized] for (osect = objfile->sections; osect < objfile->sections_end; osect++) \ ^ symfile.c:3442:23: note: 'sec' was declared here struct obj_section *sec; ^ cc1: all warnings being treated as errors make[2]: *** [symfile.o] Error 1 make[2]: Leaving directory `gdb/gdb' While the bug was reported to GCC as <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64823>, the attached patch simply initializes sec with NULL. gdb/ChangeLog: * symfile.c (unmap_overlay_command): Initialize sec to NULL. Tested on x86_64-linux.
