I've been trying to get to the bottom of a bug for a couple of days
arising in AST_TRANN when I try to convert used-supplied polar
co-ordinates to the Base Frame to check that they're valid.
When the SEGV reproduced with different NDFs and different current WCS
frames (AXIS or a SkyFrame) I suspected AST. However, given the
supplied mapping and argument values, David doesn't find the crash and
obtains sensible transformed co-ordinates.
Trying valgrind doesn't reveal (to me) any obvious problem with my code
(follows this message). The only possible leaks mention are in AST,
and I'm not sure if those are relevant because I had to break in to
complete the valgrind o/p.
Are there other valgrind tools that I should be using or vital clues
that I've missed from valgrind's report?
