Bug ID: 115290
Summary: tree check fail in c_tree_printer, at
c/c-objc-common.cc:330
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
For this C code:
$ more bug1029.c
typedef enum { SERVER_HELLO_DONE } message_type_t;
message_type_t handshakes[256][32], tls13_handshakes[256][32];
void main() { (0 ? tls13_handshakes : handshakes) == tls13_handshakes; }
$
compiled as follows:
$ ~/gcc/results/bin/gcc -c -Wall bug1029.c
does this:
bug1029.c:3:6: warning: return type of ‘main’ is not ‘int’ [-Wmain]
3 | void main() { (0 ? tls13_handshakes : handshakes) == tls13_handshakes;
}
| ^~~~
bug1029.c: In function ‘main’:
bug1029.c:3:51: warning: comparison between two arrays [-Warray-compare]
3 | void main() { (0 ? tls13_handshakes : handshakes) == tls13_handshakes;

tree check: expected tree that contains ‘decl minimal’ structure, have
‘cond_exp
r’ in c_tree_printer, at c/c-objc-common.cc:330
