MIPs Unaligned Relocation Table in libstdc++.so

[Charles Hardin]

All,
 
I couldn't find an answer to this, so I apologize if this is already known...
 
For performance reasons, I instrumented the unaligned trap handler on a Linux 2.4.25 MIPs kernel to see when it was used... Oddly enough, the instrumentation triggered on application loads that were dynamically linked to libstdc++.so...
 
What I know so far... This is a cross compile environment so "mipsel-linux" is the cross compiler...
Using gcc 3.4.1
Using glibc 2.3.2
Using binutils 2.14.90.0.8
 
# mipsel-linux-objdump -R libstdc++.so | grep "[^048c] R_MIPS"
00114fe2 R_MIPS_REL32      __gxx_personality_v0
0011598d R_MIPS_REL32      __gxx_personality_v0

This seems to be a problem to me? and it doesn't happen on an x86 compile...
 
Any pointers are appreciated...
