<pre>I know of this bug which is pretty much the same:
<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED INVALID - function declared as returning value but not returning a value results in SIGILL when executed"
href="show_bug.cgi?id=17375">http://llvm.org/bugs/show_bug.cgi?id=17375</a>
It's been declared resolved invalid but really it is an issue.
Here is my code demonstrating the issue. Could not be shorter:
int func()
{
}
int main()
{
func();
return 0;
}
Crashes with illegal instruction when compiled with clang++
It passes with clang. (the file name I used was test.c with lowercase c)
I was bitten by this using Lua. This is code I do not write. If I use a library
that does not do return, I should not have my code crash.
I think this bug is fully alive and important and not "resolved invalid"</pre>
