[Bug c++/45431] New: initializer-string for array of chars is too long: which one?

[giecrilj at stegny dot 2a dot pl]

== Steps to reproduce ==

#!/bin/sh
# 1. Create the source file
cat > 'bugpp.cpp' <<'/* EOF */'
struct personal_data 
{ char name [01]; char surname [01]; } 
const sc_me = { 
  "Christopher", 
  "Yeleighton" };
/* EOF */
# 2. Compile as C++
make 'bugpp'
# 3. Compile as C
mv 'bugpp.cpp' 'bug.c'
make 'bug'

== Expected results (from gcc) ==

cc     bug.c   -o bug
bug.c:4: warning: initializer-string for array of chars is too long
bug.c:4: warning: (near initialization for &#8216;sc_me.name&#8217;)
bug.c:5: warning: initializer-string for array of chars is too long
bug.c:5: warning: (near initialization for &#8216;sc_me.surname&#8217;)

== Actual results (from g++) ==

g++     bugpp.cpp   -o bugpp
bugpp.cpp:5: error: initializer-string for array of chars is too long
bugpp.cpp:5: error: initializer-string for array of chars is too long

== Essential differences ==

* The first line number should be 4
* g++ fails to indicate the failing data field

== Why this is important ==

Ordinary bugs in error messages should be marked as "enhancement"; however,
this one is particularly nasty.  It is very difficult to identify the cause of
error when compiling long data initialisation statements using g++ because the
error message does not contain the line number or the position in the
structure.

* Bug 31158

== Version information ==

Using built-in specs.
