I'm still unable to see all locals, but can output some of them with printf. qemu_savevm_state_iterate is called 35 times, iterates over timer, COLOState, slirp, block and ram entrys, and the error is on handling ram entry. -- You received this bug notification because you are a member of qemu-

that code should be ok; if you can find it with a debug I'd try and figure out what block and page pss is currently pointing to. Is it normal RAM or something special? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU.

Sorry, no idea - I don't know windows build/debug. (I know the migration code that savevm uses, which is why I looked at this bug) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1829242 Title: qemu

To do this I must crosscompile qemu on a linux host and debug on a windows host. Is there a gdb for 64-bit windows, since windows debuggers don't understand DWARF debugging info, and is it possible to give him paths to source files, since paths on the build machine and the debugging machine will

I think you'll have to break out a debugger on it to see why it's exiting; if you can break on any exit paths and get a backtrace we can have some more guesswork. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU.

Hi, No, no messages, no crash window which appears when windows catches unhandled exceptions in software. Looks as if there was an asynchronous command to exit during savevm which executed in parallel to the command. -- You received this bug notification because you are a member of qemu-

Hi Alex, I'm not sure we've tried a savevm on a windows host; I don't have one easily available. When you say 'after a few seconds qemu exits' - does it give any errors or crash or anything? -- You received this bug notification because you are a member of qemu- devel-ml, which is
