execution
speed? Like additional debug checks?
Not aware of any such changes.
I actually found it. I havily use core.sys.windows.stacktrace in my code
and I did make some modifications on my druntime branch which I
accidentially reverted when merging in druntime 2.063.2
These changes make stacktracing on windows faster by a factor of 10.
Thats why I see such a performance impact with dmd 2.063
I'm currently preparing a pull request for this but I ran into an issue.
When compiling the latest druntime with the latest dmd for windows
32-bit I get the following error message:
lib\druntime.lib: Error: corrupt object module
On windows 64-bit everything works fine. Any ideas why this happens?
Kind Regards
