FACT(s) (Environment):
Progress 9.1D
SYMPTOM(s):
Error running a 4GL procedure.
SYSTEM ERROR: Memory violation. (49)
Program is compiled (.r code) and resides in a memory-mapped procedure library.
Stack trace from _progres reads:
dblank
umLitGetFmtStr
CAUSE:
Progress fails while attempting to display a multi-column label containing trailing spaces. For example:
DEFINE VARIABLE v AS CHARACTER.
DEFINE FRAME fTest
v COLUMN-LABEL "test !field".
UPDATE v WITH FRAME fTest.
This is just an example: any piece of 4GL that will cause a frame to be displayed which contains any such field will crash the session with umLitGetFmtStr() and dblank() in the stack trace.
FIX:
Remove the trailing spaces from the COLUMN-LABEL phrase. For example:
DEFINE VARIABLE v AS CHARACTER.
DEFINE FRAME fTest
v COLUMN-LABEL "test!field".
UPDATE v WITH FRAME fTest.
