Halve the frequency (75 MHz) and see if they run longer than 6 hours.

No, still having the same problem at about the same frequency (no increase at all in how long they run).

Also (in less than a week) cgminer has crashed four time (I just see "segmentation fault" with the terminal back at the shell prompt.

This is starting to sound similar to what btckess experienced.
Follow his troubleshooting step(s) up to resolution from here to see if any of it relates:

I'll take a peek a Gentoo this weekend.
I use to enjoy using that, but have nearly forgotten it still existed these days.

I got through mkpart partitioning and to the step of building the kernel then it struck me why I never looked back to this flavor on linux Sad

.
Went straight to osboxes, to move things along.

In any case, I didn't see the same compile complaint you got on my first go at it.

Code:

emerge dev-vcs/git
emerge dev-libs/libusb

git clone https://github.com/vthoang/cgminer.git
cd cgminer
./autogen.sh
CFLAGS="-O2 -Wall -march=native" ./configure --enable-gekko
make -j 2

Code:

osboxes cgminer # ./cgminer -n

I'll keep tabs on it anyways and let it run for 48hrs before letting it fade away again.
