Description
Loading pdb works in profile_explorer_installer_1.1.5_x64
Release 1.2.0 and every later version breaks it (i tested all newer releases to find out in which breaks).
If it helps, i am profiling an app built using FPC compiler ( https://gitlab.com/freepascal.org/fpc/ ) that originally has dwarf symbols, but then it is converted to PDB using https://github.com/rainers/cv2pdb, the pdf file is in same directory as the application exe (it is 64 bit x86_64 binary).
This all worked fine until version 1.2.0.

Research direction
Reproduce the regression by comparing PDB loading in profile_explorer_installer_1.1.5_x64 with version 1.2.0 and later, using the 64-bit FPC application and cv2pdb-generated PDB described in the issue. Start by identifying the PDB-loading entry point and the behavior change; done means the converted PDB loads for the supplied application as it did in 1.1.5.
