Subject: Re: [b2g] b2g process segmentation fault
Hi,
Getting segmentation fault for b2g process on device ported with FFOS based on
JB 4.2.1
And in gdb prompt getting below back trace, in anyone have some idea?
(gdb)backtrace
#0 rtld_db_dlactivity () at bionic/linker/rt.c:35
#1 0x400444d2 in notify_gdb_of_load (info=0xbedfc9a4) at
bionic/linker/linker.cpp:238
#2 __dl_$t () at bionic/linker/linker.cpp:1703
#3 0x4004493c in __linker_init (elfdata=0xbedfcaf0) at
bionic/linker/linker.cpp:2047 Backtrace stopped: previous frame inner to this
frame (corrupt stack?)
Looks like bionic linker throw segmentation fault for elfdata gives
