Firefox 50.0,1_1, on FreeBSD 9 - Regular crash with Bus error 10, probably to Javascript.

I am having regular crashes with the latest Firefox. The didn't happen when
I built it -DWITH_DEBUG. Thankfully I was able to force -g using make.conf,
install it with STRIP=, and get the following backtrace.
The fault seems to be entirely with firefox, and seems to be with
overagressive optimization. Top lines of backtrace:
#0 CopySwapUTF16 (aLen=24, aOutBuf=<optimized out>, aInBuf=<optimized out>)

CopySwapUTF16() is
922 static void
923 CopySwapUTF16(const uint16_t *aInBuf, uint16_t *aOutBuf, uint32_t aLen)
924 {
925 const uint16_t *end = aInBuf + aLen;
926 while (aInBuf < end) {
927 uint16_t value = *aInBuf;
928 *aOutBuf = (value >> 8) | (value & 0xff) << 8;
929 aOutBuf++;
930 aInBuf++;
931 }
932 }
So, it seems that we are trying to dereference a value that has been
optimized out. Of course, I may be way off base.
If there is anything I can do, let me know.
Thanks,
Robert Backhaus.
