ps testfile with type1 font calling stringwidth repeatedly 

Hello,

During testing the fixes for Bug 692172 and 692127 (692290)
i noticed that since Ghostscript 9.02 the  gswin32c process
starts eating up all available memory when converting ps documents with
many pages using the pdfwrite or ps2write device.
I tracked this problem down to the stringwidth operator, when
used with some type1 fonts. This problem does not occur with Ghostcript
Versions <= 9.01 or if the -dDisableFAPI=true switch is used.
Please find attached a simple postcript program using one
of the problematic fonts and then calling repeatedly the
stringwidth operator.

Best regards,

steve166
