#12577: The flag -xb has no effect on Windows ----------------------------------------+--------------------------------- Reporter: Phyx- | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Windows Architecture: Unknown/Multiple | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #12576 Differential Rev(s): | Wiki Page: ----------------------------------------+--------------------------------- `-xb` is supposed to be used to change the base memory location for heap allocation calls. However all the calls in `rts\win32\OSMEM.c` call `VirtualAlloc` with `NULL` and not the desired start address. This makes the flag not do anything on Windows (based on quick inspection of allocated values).
