Initial Comment: as reported for the debian-package of Pd [1], pd can crash when using [tabread4~] and loading an invalid (raw) file into the table using [soundfiler].

"invalid" file means, that a (raw) file is read with a "headersize" (to skip) that is actually larger than the entire file.

[soundfiler] will attempt to resize the table to something negative (since filelength-headersize<0) which will fail safely, and leave the table at a size=1.

however, a [tabread4~] that accesses this table might segfault, since it needs more than 1 sample to interpolate.

for a patch that triggers the problem, see [1].

it seems that the problem only appears on x86_64, and not on i386.
