Re: [Valgrind-users] Valgrind/Cachegrind stack overflow problem with Wine app

[Prashant V. <pra...@ya...>]

I just reran valgrind 1.9.6-wine with the following
command line (without cachegrind):
valgrind --trace-children=yes wine ./Acrobat.exe
And this time it stopped with :
disInstr: unhandled opcode 0x94 then 0x8B

valgrind: the `impossible' happened:
   unhandled x86 opcode
Basic block ctr is approximately 91650000

This is followed by some lines of sched status.

For the stack size previously running cachegrind, I've
tried 32<<20 (thats 1<<25).I'll try with 1<<27, but I
wonder if this could point to a bug.
