psFitsReadTable() segfaults on valid input

[jhoblitt]

The code example below causes a segfault.

#include <pslib.h>

int main () {

psFits *f;
psArray *table;

f = psFitsAlloc("./phot.db");

move to first table
psFitsMoveExtNum(f, 1, false);

table = psFitsReadTable(f);

}

psFitsReadTableRow() also segfaults on the same file.

[robert.desonia@…]

Found the problem; I wasn't properly allocating a buffer for reading a string
element of a table.

Fix is in CVS.

Confirmed. I an unable to produce a segfault.
