Hi,<br>
<br>
if i build a debug version of VM on windows , it spams me with this<br>
assertion failed in debug console window:<br>
<br>
(getfp() & STACK_ALIGN_MASK) == STACK_FP_ALIGN_BYTES 41946<br>
....<br>
<br>
what is this number '41946', which follows? sometimes it is 42015 (and<br>
sometimes other), but most of times it's 41946.<br></blockquote><div><br></div><div>It is the line number of the assert that is failing. This will be in the interpreter file somewhere. This is not spam. It is a bug (and likely in NativeBoost).</div>

Actual question, how i can instruct gdb to break on a first failure of<br>
this assertion, so i can catch who causing this (or at least get close<br>
to one who causing it)..<br></blockquote><div><br></div><div>wot Mariano said.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">P.S. the STACK_ALIGN_BYTES is 16<br>

P.P.S. i wonder for how long this thing broken there, since we're not<br>
building/using debug version of VM that often.<span class="HOEnZb"><font color="#888888"><br></font></span></blockquote><div><br></div><div>I doubt it is broken in the VM. Stack alignment is very important for e.g. SSE floating-point on x86. If it were broken the VM would not work. I guess you're generating NB code that is not preserving stack alignment and on callback you're falling foul of the assert.</div>
