Bug ID: 29985
Summary: gdbtypes.h:985: internal-error: field: Assertion `idx
>= 0 && idx < num_fields ()' failed.
Product: gdb
Version: HEAD
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c++
Assignee: unassigned at sourceware dot org
Reporter: pawel_sikora at zoho dot com
Target Milestone: ---
hi,
a large c++ enum-class crashes gdb during variable printing.
(gdb) r
Starting program: /home/pawels/src/bugs/gdb-big-enum/test
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Breakpoint 1, main () at test.cpp:5
5 enumVal = ENUM_ID::ENUM_VAL_14;
(gdb) n
6 return 0;
(gdb) p enumVal
$1 =
gdbtypes.h:985: internal-error: field: Assertion `idx >= 0 && idx < num_fields
()' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
