I've not found any useful info on MSDN about a 32 KiB limit on winhttp chunk size. Maybe the MS guys who wrote the installer made some assumption about some underlying native winsock implementation limitation on Windows. It might be interesting to see what max. chunk size native winhttp reports to clients.

Opcode_2=2 register "TPIDRURW" is "Software Thread ID, User, R/W" Not sure if this is a "free for use" register or if any user space threading library code actually manages this register. One would have to search eglibc sources for ARM and any userspace libraries mapped into process address space, not part of Wine. The values don't seem very random but they point to invalid (not mapped) memory locations. I couldn't find any MCR opcodes in application code, so it's probably written elsewhere. This linux kernel patch has a bit of information: http://www.kernelhub.org/?p=2&msg=57979 It got committed to Linux 3.3.5: http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.3.5 (search for TPIDRURW). I'm running 3.2.0 so it's obviously not cleared by kernel side on context switch. Anyway, I fear this will be most likely upstream if the kernel deliberately clears it on every context switch (starting with 3.3.5). $ du -sh rtools_setup_arm.exe 16M rtools_setup_arm.exe $ sha1sum rtools_setup_arm.exe 6f75e6dad60b64e1f074884829b63ca00bcdb531 rtools_setup_arm.exe Regards -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
