The attached program produces incorrect results in gcc-4.3.2 with -O2. (The
results are correct at -O0 when inline functions are not used).
The code evaluates a complex polynomial in Horner form via an inline function.
It is part of the test suite of gsl-1.11 (GNU Scientific Library). I have

Note that the reason the diagnostic happens is either a bug in libstdc++ or
the points-to solver or the TBAA pruning in the points-to solver.
In the end we access the object 'ctx' via a pointer of type
const struct

Hi, I can not reproduce this Bug on FreeBSD. May be it is just not detected.
Can you try with current graphite branch to see it was a duplicate of Bug38459.
Otherwise I will have to try it on Linux with valgrind

The relevant path through the CFG is
struct test ctx;
bb 2:
# ctx_108 = VDEF ctx_103(D)
# SMT.120_109 = VDEF SMT.120_104(D)
# SMT.121_110 = VDEF SMT.121_105(D)
# SMT.122_111 = VDEF SMT.122_106(D)

working s-scaval.adb
Not much. Just an empty version of s-scaval.adb that lets the build proceed
past this point.
Would be useful to have the sentinel attribute functionalities but for things
other than a NULL pointer. Something like:
__attribute__(sentinel_custom((int*) -1))
