Untested patch. Not 100% sure if there must be just one landing pad, will see
during boots

Ah, the #c13 testcase shows the issue, but in the early inliner, not in IPA
inliner like is triggered on the #c7 testcase.
This modified testcase triggers it in the IPA inliner:
typedef __SIZE_TYPE__ size_t;

Short testcase that shows what's going on on the #c7 testcase:
typedef __SIZE_TYPE__ size_t;
struct A { A (); ~A (); int a; void qux (const char *); };
int bar (char *);
static inline __attribute__((always_

Unreduced test case
There; unreduced, from public MySQL. This is preprocessed with GCC 7, and
compiles b

--- Comment #6 from Steinar H. Gunderson ---
I wouldn't be surprised if everything is really over-reduced, and that GCC 7
just happens not to hit this by luck.
I'll be making a checkout of the public git repository and try to reproduce
there, so

--- Comment #5 from Alexander Monakov ---
Sorry, this still seems over-reduced: the 'cmp' variable is uninitialized, and
gcc-7 completely optimizes out the block with large stack usage guarded by 'cmp
== 0' test, so gcc-7 vs gcc-8 is not directly

--- Comment #4 from Steinar H. Gunderson ---
New test case added. It's quite a bit larger than the old one, but has no
-Wreturn-type warning.

OK, starting a reduce that also checks for no -Wreturn-type warnings.
