Im getting a runtime memory error when trying to resize table to a non-power\_of\_2 size although I put a minus in f statement: `csound.inputMessage(`f 1 0 -132320 -2 0`);`

Console output:

```csound
Loading 132320 samples into table gi_tab_sample
**Current table size: 4 samples**
Csound stopped for table resizing
 	T 8.952 TT 8.952 M: 0.00000 0.10000

    currently active instruments may find this disturbing

ftable 1:

ftable 1:	132320 points, scalemax 0.000
**Resized table size: 132320 samples**

```

As you can see, the table resizing is successful but this error is thrown and stops csound.

Im working with latest @csound/browser 7.0.0-beta20 version but I also tested it with 6.18.5 and the issue is there too.

Am I missing something? Is there maybe a better way to resize a table in runtime?

Very slow reply (9 months late), this was likely a native csound bug that has been fixed in latest beta release.

Thanks @hlolli for reply! Oh that dynamic memory allocation 🫪
