[Bug binutils/17541] addr2line: function names in anonymous namespaces are incorrectly reported.
https://sourceware.org/bugzilla/show_bug.cgi?id=17541 Alan Modra changed: What|Removed |Added Status|NEW |ASSIGNED Assignee|unassigned at sourceware dot org |amodra at gmail dot com --- Comment #1 from Alan Modra --- This is because bfd/dwarf2.c doesn't decode the pertinent C++ DWARF information. The reason the old binutils "works" when given an object compiled by a new gcc is (at a guess) due to not decoding the DWARF, and thus falling back to looking at the symbol table. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
