Hi all, Since at least three monthes a bug pops in and pops out in an erratic way while running dostest.bat after a new compilation of a gpc snapshot under djgpp-2.95.2 (nothing to do with the recent discussion about 2.95.3: I have reverted to 2.95.2). It is in one or both of the test programs nicola1.pas and/or nicola2.pas. On the screen (and in the make.out logfile) I have: --------------------------------------------------- Running the GPC Test Suite. This may take a while... NOTE, if you've used the Test Suite before: To get the long output format, run `make pascal.check-long' now.

It may be completely unseen on other systems.
