Support Fibers API
Currently, Performance Profiler causes program crash when profiling code using Fibers API (see Case #00169159: Program halts when run under Performance Profiler). To reproduce: 1) Compile attached Delphi program. Note it uses Fiber API to implement generator: https://msdn.microsoft.com/en-us/library/ms682661.aspx 2) Run it. The output is 2 3 5 3) Open in AQTime, select Performance Profiler, All Project Modules. Run. The program halts. Event View window shows: Event Thread ID Time Project run selected, current profiler is Performance Profiler. 18:27:24:533 Process create ID: 5572, Thread ID: 8316, Base address: 0x00400000 8316 18:27:24:544 Module loaded: fiberdemo.exe;
