Comment(by kurahaupo):
Firstly, I notice that the array is always missing 1920 elements, even if
I double the size to 200000.
Secondly, when I instrumented Parrot_pmc_array_unshift (by putting a
"printf" in the conditional block where "start" is 0) it actually failed
during the build, at
./parrot -o runtime/parrot/include/parrotlib.pbc
runtime/parrot/library/parrotlib.pir
in much the same manner, after just two "unshift" chunk insertions.
However since I still had runtime files from the unadulterated build, I
could still run the test file.
It's possible that the instrumentation itself causes the new form of
error, but I would like to investigate whether GCC is over-optimizating
something.
