Bug #: 54205
Summary: recursive .debug_macro inclusions
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: tromey@gcc.gnu.org

readelf output
I built git master gcc today.
Then I ran the libstdc++ pretty-printer tests.
One of these tests (48362.cc) caused gdb to die, so I investigated.
It turns out that gcc is emitting recursive DW_MACRO_GNU_transparent_include
calls in .debug_macro. I previously thought I fixed this problem in
http://sourceware.org/bugzilla/show_bug.cgi?id=13568
-- but the fix was insufficient; and in any case I think gcc should not do
this.
I'm attaching the readelf dump of the section so you can see the issue.
