Summary: Bug with empty C99 structure initialization
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
I don't known if it's a clang or llvm bug:
#cat bug-struct-c99.c
struct E {};
struct G { int I; struct E J; int K; };
struct G k = { .J = {}, 1 };
int main (void)
{
if (k.I || k.K != 1 )
abort ();
exit (0);
}
#clang bug-struct-c99.c
Abort
The bug in the generated assembly is here:
#clang bug-struct-c99.c -S -o -
[...]
k:
.long 0
.zero 1
.long 1
.size k, 8
it should be:
k:
.long 0
.long 1
.size k, 8
