Yes, I don't mean to suggest that the build will fail every time time in every environment. I have one particular environment where I can make it occur reliably, but it may not do so elsewhere. I noticed that setting "-Doptimize='-O2'" makes the problem go away in my environment, for example. As I wrote in my commit message, I believe the cause of these symptoms is an additional dependency on Cwd added in 3dfcef7e97bf1b516f that has not been reflected in the build system. I believe my patch addresses that, although I recognise it might do so suboptimally or inelegantly. TomThread Previous | Thread Next
