(gdb) maint expand-symtab dw2-symtab-includes.h^M /home/vries/gdb_versions/devel/src/gdb/dwarf2/read.h:311: internal-error: unit_type: Assertion `m_unit_type != 0' failed.^M A problem internal to GDB has been detected,^M further debugging may prove unreliable.^M ----- Backtrace -----^M FAIL: gdb.dwarf2/dw2-symtab-includes.exp: maint expand-symtab dw2-symtab-includes.h (GDB internal error) ... The assert was recently added in commit 2c474c46943 ("[gdb/symtab] Add get/set functions for per_cu->lang/unit_type"). The assert is triggered here: ... /* We're importing a C++ compilation unit with tag DW_TAG_compile_unit into another compilation unit, at root level. Regard this as a hint, and ignore it. */ if (die->parent && die->parent->parent == NULL && per_cu->unit_type () == DW_UT_compile && per_cu->lang () == language_cplus) return; ... We're trying to access unit_type / lang which hasn't been set yet. Normally, these are set during cooked index creation, but that's not the case when using an index (or using -readnow). In other words, this lto speed optimization only worked in the normal usage case. -- You are receiving this mail because: You are on the CC list for the bug.
