No debug info on C-style unnamed structures

[Anonymous]

It seems that VisualGDB incorrectly interprets information about structures defined in C-style. If some structure contains unnamed structure as a first member, then no debug information will be provided.

At the same time in GDB Session it is possible to retrieve information manually.

p st
&"p stn"
$1 = {{member1 = -139589008
, member2 = -1 '377'
}
, member6 = 4196992
}

Hi,

When you hover over st, what is VisualGDB calling from gdb and what is its response (also in the GDB Session window)? Is it the same as the command you run manually?

Hello,

I got following interaction log (hovered on st, then expanded):

-var-create --frame 0 --thread 1 - * "st"
^done,name="var2",numchild="1",value="{...}",type="MyStruct",thread-id="1",has_more="0"
-var-list-children --simple-values "var2" 0 1
^done,numchild="1",children=[child={name="var2.public",exp="public",numchild="2",value="",thread-id="1"}],has_more="0"
-var-list-children --simple-values "var2.public" 0 2
^done,numchild="2",children=[child={name="var2.public.",exp="",numchild="1",type="struct {...}",thread-id="1"},child={name="var2.public.member6",exp="member6",numchild="0",value="4196992",type="int",thread-id="1"}],has_more="0"
-var-list-children --simple-values "var2.public" 0 2
^done,numchild="2",children=[child={name="var2.public.",exp="",numchild="1",type="struct {...}",thread-id="1"},child={name="var2.public.member6",exp="member6",numchild="0",value="4196992",type="int",thread-id="1"}],has_more="0"

By the way the same issue affects Watch and Auto windows.

Hi,

We have looked into it and added a workaround to VisualGDB 4.1r7. Please note that you can also resolve this issue by updating your GDB to 7.6.

Hello,

Thank you for fast turnaround! Both solutions worked for me.
