It also happens that std::lower_bound returns a pointer exactly at the upper bound of the line table, also here the read value is undefined, that happens in this test: FAIL: gdb.dwarf2/dw2-epilogue-begin.exp: confirm watchpoint doesn't trigger Fixes: 528b729be1a2 ("gdb/dwarf2: Add support for DW_LNS_set_epilogue_begin in line-table") Co-Authored-By: Tom de Vries <tdevries@suse.de> PR symtab/31268 Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=31268 -- You are receiving this mail because: You are on the CC list for the bug.
