Summary: Wrong language selected when DW_AT_language tag is
missing from the DWARF header
Product: gdb
Version: 7.2
Status: NEW
Severity: normal
Priority: P2
Component: symtab
AssignedTo: unassigned@sourceware.org
ReportedBy: JPEWdev@gmail.com
Created attachment 5213
--> http://sourceware.org/bugzilla/attachment.cgi?id=5213
Example Patch file
If the header for a compilation unit is missing the DW_AT_language, the
language for the compilation unit is set to ADA (at least for GDB version 7.2).
Searching through the code, the problem appears to be located in dwarf2read.c.
There are several places where set_cu_language() is called like so:
attr = dwarf2_attr (cu->dies, DW_AT_language, cu);
if (attr)
set_cu_language (DW_UNSND (attr), cu);
else
set_cu_language (language_minimal, cu);
Since set_cu_language() maps a DWARF Language constant to an internal language
type, passing language_minimal as the first parameter when the tag cannot be
found is incorrect.
A suggested patch for the 7.2 code is attached.
