Hello.
I had a segfault with current version of flashrom, and with some help
from stefanct at IRC i was able to bisect it down to r1833.
I attach backtraces.
Roman.

(gdb) r --programmer internal -r 1002.bin
Starting program: /usr/local/sbin/flashrom --programmer internal -r 1002.bin
flashrom v0.9.7-r1833 on Linux 3.16.0-4-686-pae (i686)
flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK.
Active config mode, unknown reg 0x20 ID: 00.
Please send the output of "flashrom -V -p internal" to
flashrom at flashrom.org with W836xx: your board name: flashrom -V
as the subject to help us finish support for your Super I/O. Thanks.
Found chipset "Intel 6300ESB". Enabling flash write... OK.
Found PMC flash chip "Pm49FL004" (512 kB, LPC, FWH) at physical address 0xfff80000.
===
This flash part has status UNTESTED for operations: ERASE WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to flashrom at flashrom.org if any of the above operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -Vr,
-VE, -Vw), and mention which mainboard or programmer you tested.
Please mention your board in the subject line. Thanks for your help!
