EurekaLog causes AccessViolation?

We were contacted by a person who complained that his application was working fine until he added EurekaLog to it. An AccessViolation exception was raised after adding EurekaLog to project. The message was: "Access violation at address 00E15025 in module 'Project.exe'. Read of address 83EC8B69". And the stack was:

• Contoso.pas TContosoEventMessage.BasePerform
• Vcl.Forms.pas TApplication.WndProc
• System.Classes.pas StdWndProc
• Vcl.Forms.pas TApplication.HandleMessage
• Vcl.Forms.pas TApplication.Run
• Project.dpr Initialization

(all names have been replaced; Contoso represents some well-known library for Delphi).
