...he dynamic linker or something in Postgres that's interfering with
the coverage feedback but it's exiting after one call thinking the
newcoverage isn't increasing over the previous coverage.
The test that causing it to exit is at FuzzerLoop.cpp:250
if (NewCoverage > OldCoverage || NumNewBits)
return NewCoverage;
250 if (NewCoverage > OldCoverage || NumNewBits)
(gdb) p NewCoverage
$3 = 14422
(gdb) p OldCoverage
$4 = 14422
(gdb) p NumNewBits
$5 = 0
And after that it just returns.
In fact the only call it makes to my test function is with Data=NULL
Size=NULL which isn't a v...
