PRB: Profiler Fatal Errors PRF1012 and PRF1306

The information in this article applies to:

• The Microsoft Source Profiler, included with: Microsoft Visual C++, 32-bit Edition, versions 2.0, 2.1, 4.0, 4.1, 4.2

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

SYMPTOMS

When trying to profile an application using Visual C++'s development environment, you get the following fatal error messages:

   PROFILE.DLL : fatal error PRF1012 : cannot read expected number of
   bytes from file <path>\xxxx.pbi

   PREP : fatal error PRF1306: PBT or PBO file <path>\xxxx.pbo is not
   derived from same PBI file

  It is also possible to get the following error if you are using the
  incorrect PROFILE.DLL:

   PROFILE.DLL: fatal error PRF1005: operating system ran out of memory.

CAUSE

The wrong version of PROFILE.DLL is being loaded in memory and used by the profiler. Most likely a copy of PROFILE.DLL from Visual C++, 32-bit Edition, version 1.0 has been loaded by Windows NT.

RESOLUTION

Make sure the PROFILE.DLL from Visual C++ version 2.0 or 2.1 is used by the profiler. Do a file search on your system to determine where the older PROFILE.DLL is located, and rename or delete the file. Make sure that the only PROFILE.DLL on your system is located in Visual C++'s BIN directory.

If for some reason there is no PROFILE.DLL in the BIN directory, you can restore the file by running Visual C++'s setup program and doing a custom installation. To do this, unselect all options except for 'Profiler' in the

'Tools Options' dialog. You also need to make sure the installation

MORE INFORMATION

The incorrect PROFILE.DLL will probably be found in the <winnt>\SYSTEM32 directory where <winnt> refers to the directory that Windows NT is installed. Or the DLL may be in another directory found on the PATH. The correct file should be located in the Visual C++ 2.x BIN directory.
