[Pkg-acpi-devel] Bug#579988: acpitool: segfault when battery.patch is applied

[Patrice Dumas]

Package: acpitool
Version: 0.5.1-1
Severity: important


When I start the debian acpitool, without argument, I get an immediate 
segfault. Upstream pristine acpitool doesn't segfault. It segfaults after
applying battery.patch.

Here is the backtrace (when only battery.patch is applied, not the 
other debian patch):

gdb) run
Starting program: /home/dumas/tmp/acpitool-0.5.1/src/acpitool 

Program received signal SIGSEGV, Segmentation fault.

#6  0x0804a439 in main (argc=1, argv=0xbffffb04) at main.cpp:237

My wild guess is that it is the space in the line of
/sys/class/power_supply/BAT0/uevent:
POWER_SUPPLY_MODEL_NAME=DELL Y13386
that causes the segfault.
