Package: lazarus-ide Version: 0.9.28.2-7 Severity: wishlist Tags: patch Find attached a patch that avoids trapping some FPU exceptions, since C code handles them differently, or that the CPU exception flag is leftover from the C library function call which C code wouldn't bother but FPC needs it to be explicitly cleared upon the function return.
