The information in this article is included in the documentation starting with Visual C++ 5.0. Look there for future revisions.



SYMPTOMS
Running the Microsoft Source Profiler PROFILE command in the MS-DOS or Microsoft Windows operating system on an application that contains P-code causes the following error:

PROFILE: fatal error PR1428: A user-defined breakpoint was found at location



CAUSE
The fatal error PR1428 is generated because the P-code breakpoint instruction is implemented as Interrupt 03h, which cannot be profiled (as stated on pages 73 and 75 of the Source Profiler &quot;User's Guide&quot; for version 1.2). Using Interrupt 03h in an application conflicts with the way that the Source Profile itself uses Interrupt 03h.



RESOLUTION
To avoid this fatal error, profile the application after removing all the P- code from the profiled region.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Source Profiler version 1.2 for MS-DOS and Windows. This problem was corrected in Microsoft Source Profiler version 1.3.
