Summary: load library like libosipparser2.so.4 sometimes fails on trunk head built by gcc 4.3

Details:

load library like libosipparser2.so.4 sometimes fails on trunk head. This happens in linphone testing. For the first time loading, it can't find the library, while the second time to run linphone, it can find it then.

For those cases mapping/loading library fail, tracing log:

[kernel]

do_filp_open file:02beb4c0 filename:/usr/lib/libosipparser2.so.4

do_mmap2 file:02beb4c0 addr:00000000 pgoff:0 len:22b24 mmaped addr:01000000

prot:5 flags:2

[user]

linphonec:582: can't map '/usr/lib/libosipparser2.so.4'

[kernel]

do_filp_open file:02beb340 filename:/usr/lib/libosipparser2.so.4

do_mmap2 file:02beb340 addr:00000000 pgoff:0 len:22b24 mmaped addr:00980000

prot:5 flags:2

[user]

linphonec:582: can't map '/usr/lib/libosipparser2.so.4'

linphonec: can't load library 'libosipparser2.so.4'

For failure library, user will call sys_mmap2 to same offset twice, everytime

kernel will return success, but user print failure. For successful library, I

only saw one sys_mmap2 to a same offset.

Then need to trace ld to find the reason. Keep Jie in the loop too.

--- Barry Song 2010-01-13 03:15:31

A check-in in toolchain close to svn 3771 has caused this problem.

--- Vivi Li 2010-01-15 02:24:58

Refer to bug [#5823], gcc4.3 svn 3679 is OK.

--- Mingquan Pan 2010-02-20 05:21:33

When testing feature reserve memory in fdpic kernel, it would fail to start at

init sometimes.

The kernel is quite normal and the only difference is the newly set bootargs in

u-boot.

In reserve memory testing, after set bootargs to reserve the 32M memory, it also

need to run addip, which makes this bug reproduce almost everytime.
