Re: gm convert bla.jpg bla.pdf multiplies SEVENFOLD the file's size !

And what does

   info locals

say?

It is pretty likely that compiler optimization will cause useful 
values not to be available.   The most useful variables to know about 
in this case are 'x', 'y', 'index' and 'q'.  In particular, either the 
storage for the memory accessed via 'q' is being over-run or the 
system is not able to provide the memory that it already allocated.

Linux uses lazy memory allocation so malloc() can report success but 
then the system can still run out of memory while the memory is being 
updated.
