[Bug inline-asm/24761] New: Missing register load before inline asm in templated function causes SIGSEGV


I have a templated function which uses inline assembler (with MMX
instructions). Inline assembler is passed pointer to array element.
When this function is instantiated for the first time, code before inline
assembler is generated correctly. When it is instantiated for the second time,
one of registers used in inline assembler is not loaded from stack and causes
segfault when it is dereferenced in inline assembler.

I will attach test case.
