Bug ID: 37885
Summary: static object mangling conflicts
Assignee: unassignedclangbugs at nondot.org
Reporter: zhonghao at pku.org.cn

I found that gcc+ produces errors when it compiles the following code:
extern "C" void abort();
static int i;
int *p = &i;
extern int i;
i = 1;
*p = 2;
if (i == 2)
When compiling the above code, clang++ does not produce any errors. The code
comes from https://bugs.llvm.org/show_bug.cgi?id=5966
Indeed, the situation is more complicated. The above bug report of clang says
that the code comes from a bug report of gcc:
I reported the difference to gcc:
After reading the bug report, Richard Biener made the following comment: "I
think the clang bug is incomplete and misses the 2nd TU which defines i. So
GCC works (and the testcase is in the testsuite)."
Is this a recurring bug in clang? Hope that the comment from Richard Biener can
further improve clang.
