Bug ID: 16435
Summary: Assertion `!value_lazy (var->value)' failed
Product: gdb
Version: 7.6
Status: NEW
Severity: normal
Priority: P2
Component: c++

C++ code which causes GDB to crash in line 18

I debug a C++ algorithm in Eclipse with GDB. With the attached code I can
reliably reproduce the following GDB crash:

../../gdb/varobj.c:3548: internal-error: c_value_of_variable: Assertion
`!value_lazy (var->value)' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

Versions:
OS: openSUSE 13.1
GDB: 7.6.50.20130731
GCC: 4.8.1

I apologize this bug has gone without response for over four years. I saw the
reclassification of this to varobj and decided to take a peek.

Unfortunately, without more information, it is not likely there is anything we
can do. While I've tried to guess at what Eclipse was doing when the assertion
happened, I have been unable to trigger this [using a 7.6 release].

So to start, is this still a problem with a recent release like 8.0 or 8.1?

If it is, could you please attach the output of Eclispe's logging? That would
really help me reproduce the exact problem you are reporting.
