problem: H5Pset_sizes(fcpl_id, offset, length) crashes
HDF5 Version: 1.10.6
When either of the values take on value 16
library crashes, tested against HDF5 1.10.6, others maybe affected
size_t offset[] = {2,4,8,16};
size_t length[] = {2,4,8,16};
size_t N = 4;
for( size_t i=0; i<N; i++) {
for( size_t j=0; j<N; j++ ) {
sprintf(name, "name_%ld_%ld.h5", offset[i], length[j]);
fcpl_id = H5Pcreate(H5P_FILE_CREATE);
err = H5Pset_sizes(fcpl_id, offset[i], length[j]);
fd_id = H5Fcreate( name, H5F_ACC_TRUNC, fcpl_id,H5P_DEFAULT );
H5Pclose(fcpl_id);
H5Fclose(fd_id);
}
}
}
output of make test
cc main.c -lhdf5 -lz -ldl -lm -o set_sizes
./set_sizes
free(): invalid pointer
Makefile:12: recipe for target 'test' failed
make: *** [test] Aborted (core dumped)
Change size_t N=4
to size_t N=3
tp reduce test range from {2,4,8,16} X {2,4,8,16}
to {2,4,8} X {2,4,8}
notice the missing 16
which is valid input according to documentation.
