Description Shamil Kurmangaleev 2010-06-18 13:41:20 UTC 
I'm try build modules for eina:
 
arm-as eina_chained_mempool.s -o chain.o
arm-ld chain.o --eh-frame-hdr -shared -dynamic-linker /lib/ld-linux.so.3 -X -m
armelf_linux_eabi -o
./shared/build/eina/src/modules/mp/chained_pool/.libs/eina_chained_mempool.so
/usr/lib/crti.o /usr/lib/gcc/arm-linux-gnueabi/4.3.2/crtbeginS.o
-L/home/kursh/arm/arm-linux-gnueabi/lib -L/home/kursh/arm/evas/shared/run/lib
-L/usr/lib/gcc/arm-linux-gnueabi/4.3.2
-L/usr/lib/gcc/arm-linux-gnueabi/4.3.2/../../../../arm-linux-gnueabi/lib -L/lib
-L/usr/lib -rpath /home/kursh/arm/evas/shared/run/lib -leina -ldl -lrt -lm
-soname eina_chained_mempool.so -lgcc --as-needed -lgcc_s --no-as-needed
-lpthread -lc -lgcc --as-needed -lgcc_s --no-as-needed
/usr/lib/gcc/arm-linux-gnueabi/4.3.2/crtendS.o /usr/lib/crtn.o

A shared library linked with gold (GNU Binutils 2.20.51.20100618) causes
segmentation fault, because GOT entry for some function is zero, while shared
library linked not gold version ld, all work fine.
Gdb says:
0x00000000 in ?? ()
(gdb) bt
#0  0x00000000 in ?? ()
#1  0x40023edc in _GLOBAL_OFFSET_TABLE_ () from /home/.../eina_chained_mempool.so

Bug maybe related to PR 11172.

Comment 2 Doug Kwan 2010-08-03 20:11:57 UTC 
Your testcase needs other libraries.  Can you attached two copies of 
eina_chained_mempool.so, one linked with gold and the ld?
