Hi,
I have compiled and generated a C++ shared library with the "-fPIC" option.
But this shared library requires text relocation during runtime and is not
usable on seLinux which disables writeable text segments. The text relocation
is due to use of exceptions inside the shared library. There is a segment
".gcc_except_table" created in the shared library and it contains symbols
suffixed with "$$LSDA" :-
0013df38 <_ZN6comref4runt11userdef20releasebackEPS1_$$LSDA>:
13df38: ff 00 incl (%eax)
13df3a: 18 01 sbb %al,(%ecx)
13df3c: 0c 1c or $0x1c,%al
13df3e: 03 2f add (%edi),%ebp
13df40: 01 52 0a add %edx,0xa(%edx)
13df43: 6d insl (%dx),%es:(%edi)
13df44: 00 66 1a add %ah,0x1a(%esi)
13df47: 00 00 add %al,(%eax)
13df49: 02 00 add (%eax),%al
...
13df4b: R_386_32 _ZTIN6comref4runt12genExceptionE
Can someone please help in understand the issue and how to work around?
Thanks,
Shankar
