What do do with EXC_ARM_DA_ALIGN on an iPhone app

Recently got the following nasty notices in a crash report on an iphone app:

Exception Type: EXC_BAD_ACCESS (SIGBUS)

Exception Codes: EXC_ARM_DA_ALIGN at 0x078e0032

Turns out that ARMv7, which is now compulsory, has memory alignment issues that ARMv6 didn't, so now people will probably see more of these issues.

Anyway, i could write about it, or i could post some links to helpful blogs:

Basically, replace code like this:

destination = *((long *)unalignedPointer);

With this:

long tmp;

memcpy(&tmp, unalignedPointer, sizeof(tmp));

destination = tmp;
