[Tinycc-devel] Crash after "warning: storage mismatch for redefinition of 'L' "

[Pascal Cuoq]

In both version 0.9.25 and today's git version (commit 
d27ea5155f47cb0c29699ef959b52b087dfff41a), tcc crashes while compiling the 
following one-line invalid program:

enum myenum { L = -1 } L;

tcc crashes after emitting an error message:

address@hidden:~/tcc-2019-02-07$ bin/tcc -c enum.i 
enum.i:1: warning: storage mismatch for redefinition of 'L'
Erreur de segmentation

GCC and Clang also consider the program as invalid, and emit the following 
messages:

address@hidden:~/tcc-2019-02-07$ clang -c enum.i
enum.i:1:24: error: redefinition of 'L' as different kind of symbol
enum myenum { L = -1 } L;
                       ^
enum.i:1:15: note: previous definition is here
enum myenum { L = -1 } L;
              ^
1 error generated.
