re PR debug/52027 (ICE: SIGSEGV in set_cur_line_info_table (dwarf2out.c:20428) with -O -freorder-blocks-and-partition -fno-reorder-functions -fprofile-use)
PR debug/52027
* dwarf2out.c (dwarf2out_switch_text_section): Don't call
set_cur_line_info_table if not emitting debug info.
* gcc.dg/tree-prof/pr52027.c: New test.
