Delta IV Heavy Launch

That would require a catastrophic _rise_ in chamber pressure, not a drop. If the chamber pressure drops on the SRB, it's not going to cause it to explode. (in fact, if it's severe enough it could cause combustion to cease in the SRB - that was the concept used on the SRBs developed for the Titan III C variant that was going to be used on Dyna-Soar and MOL, which had blowout vents mounted at the top of the casing.) That's actually a safety feature (of sorts), when the pressure drops the combustion rate also drops. In theory this makes being around a solid 'safer' and makes emergency response in the vicinity of a recently violently disassembled solid 'easier'. D. -- Touch-twice life. Eat. Drink.
