Strange thread crash (inline, loop unrolling)

[barsmonster]

Hi, I am experiencing strange compilation issue, quick code overview:

Version: Intel C++ 11.1.046

void check_block_sse2(unsigned int *data_d, unsigned int pwd_len, int charset_len, int keys_per_thread, int* result)
{
for(int key_pos=0;key_pos {
check_block_sse2_inline(key_pos, data_d, pwd_len, charset_len, keys_per_thread, result);
}
}


__forceinline void check_block_sse2_inline(int key_pos, unsigned int *data_d, unsigned int pwd_len, int charset_len, int keys_per_thread, int* result)
{
//Do calculate 12 MD5 hashes via SSE2 intrinsincs, alot of code skipped
//Result hashes are in a_int e.t.c
for(int i=0;i checkHashList(a_int,b_int,c_int,d_int,result[key_pos+i]);
}

__forceinline void checkHashList(unsigned int a, unsigned int b,unsigned int c, unsigned int d, int &result)
{
//If I uncomment next line - everything works as expected.
//If it is commented - thread silently exits
//for(int i=0;i<2;i++)
if(a==b)
result = KEY_FOUND;
}

Any clues what might cause it?
If there is no __forceinline it works fine anyway, but I really need this inlined for performance.

Basically, if there are some loops in checkHashList - it works fine, and my original non-simplified code in checkHashList with some while loops works fine, the problems is here only when I am getting rid of loops (for example, if I replace while with if - it starts to silently crash. No side effects).

I cannot find an error in disassembly, as it is inlined and kinda scrambled due to loop unrolling (and again, without inlining it is fine).

Any clues?

what options are used for compiling?

also there're newer updates available 11.1.051. Please try it.
You can download from our registration center or the eval center.
