ollydbg:
Some debug realize that the parser go to an infinite loop around the file x86_ops_bit.h, and around line 133, which is in a macro definition.

--- Code: ---#define opBT(name, operation) \

   tempc = (temp & (1 << (regs[reg].w & 15))) ? 1 : 0; \

opBT(C, ^=)
opBT(R, &=~)
opBT(S, |=)

--- End code ---

And from the Parserthread, I see that the m_Str becomes a very big string, it becomes bigger and bigger in this infinite loop...

--- Code: ---[debug]> p m_Str
[debug]$3 = "int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int "...
[debug]>>>>>>cb_gdb:

$3 = "int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int int "...
> p m_Str.size()

[debug]> p m_Str.size()
[debug]$4 = 131788
[debug]>>>>>>cb_gdb:

--- End code ---

But currently I don't find the deeper reason about this infinite loop.

ollydbg:
Also, those two values are surely wrong.

--- Code: ---[debug]> whatis m_RepeatReplaceCount
[debug]type = size_t
[debug]>>>>>>cb_gdb:
[debug]> output &m_RepeatReplaceCount
[debug](size_t *) 0x90d7d70>>>>>>cb_gdb:
[debug]> output m_RepeatReplaceCount
[debug]65898>>>>>>cb_gdb:
[debug]> whatis savedReplaceCount
[debug]type = int
[debug]>>>>>>cb_gdb:
[debug]> output &savedReplaceCount
[debug](int *) 0xe09fca8>>>>>>cb_gdb:
[debug]> output savedReplaceCount
[debug]65896>>>>>>cb_gdb:

--- End code ---

ollydbg:
I add some sanity check for macro expansion code in rev 9601, this avoid the infinite loop, please test and report back, thanks.

Conker:
Can you link me to the binary with that fix ?
