Examine local variable in a MacOS minidump?

[Helen Li]

Hi Chromium-dev,

I have a MacOS minidump. http://dev.chromium.org/developers/crash-reports#TOC-Extracting-Local-Variables-on-POSIX has a 8-step recommendation for how to get the local variable out of a POSIX minidump.  Examining local variables in a Windows minidump is straightforward with WinDbg, is there a similar way to do it on Mac? 

If there's no new tool, I will follow the 8-step instruction.

void URLFetcherCore::DumpWithoutCrashing() const {

   ...

   base::debug::Alias(&stack_size);

   base::debug::Alias(&instruction_pointers_copy); <-- I would like to read this from the MacOS minidump.

   base::debug::DumpWithoutCrashing();

}

Thanks!

Hi Helen,

No, there are no tools to automatically extract stack variables from minidumps on Mac. You'll either need to manually examine the stack memory to recover it (assuming your data is on the stack, otherwise you won't be able to recover it), or you can use crash keys: http://dev.chromium.org/developers/debugging-with-crash-keys.
