https://msdn.microsoft.com/en-us/library/windows/desktop/ms686774(v=vs.85).aspx indicates that the default stack size for threads is 1 MB on Windows. Even if the problem is that changing the main thread's stack size increases the default for threads, too, it still seems that both defaults on 32-bit Linux are already higher. On 32-bit Ubuntu, ulimit -s prints 8192, so the default for the main thread is 8 MB. http://man7.org/linux/man-pages/man3/pthread_create.3.html says that the default stack size for threads on 32-bit x86 is 2 MB. If we can get away with 2 MB stack size for threads that don't ask for a custom stack size on 32-bit Linux, I'd hope we don't need to treat 1 MB as a hard limit on 32-bit Windows. Or is there something that makes our default thread stack smaller than the manual page says on 32-bit Linux? -- Henri Sivonen hsivo...@hsivonen.fi https://hsivonen.fi/ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
