           Summary: Out of virtual memory space while generating symbolic
                    stack dump in chromium unit_tests.exe
           Product: Wine
           Version: 1.1.32
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: download, source
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org

If chromium's unit_tests.exe happens to crash, wine
takes a lot of memory while generating a crash dump.
Under Valgrind, it sometimes runs out of memory, with the error

"Valgrind's memory management: out of memory:
newSuperblock's request for 6295552 bytes failed.
3682476032 bytes have already been allocated.
Valgrind cannot continue.  Sorry."

For what it's worth, there are lots of valgrind warnings
during the production of the stack dump.  Here's the first one:
