Here's a reduced testcase for i686-pc-liux-gnu. Just compile with
gcc -O2 to see a linker failure:
======================================
enum { e0, e1, e2, e3, e4, e5 } e;
int main()
{
for (;;)
{
switch (e)
{
case e0:
case e1:
return 1;
case e2:
case e3:
return 0;
case e5:
e = e4;
}
}
}
======================================
/tmp/ccYklAp3.o(.text+0x46): In function `main':
: undefined reference to `.L10'
collect2: ld returned 1 exit status
