@Matthias Klose:
I think it is well possible to test this without any Nvidia hardware:
you probably can just do
$ dpkg-deb -x nvidia-glx-185_185.18.36-0ubuntu2_i386.deb xxx
$ LD_LIBRARY_PATH=$PWD/xxx/usr/lib glxinfo
and observe the crash -- it occurs on shared library load, very likely
before Nvidia's GL library even tries to access the HW. Consider also:
$ cat test.c
int main() { return 0; }
$ gcc -o test test.c -lGL
$ LD_LIBRARY_PATH=$PWD/xxx/usr/lib ./test
Segmentation fault (core dumped)
It crashes before reaching main(). Also, something strange is going on
here:
$ LD_DEBUG=all LD_LIBRARY_PATH=$PWD/xxx/usr/lib ./test
[clip]
6922: symbol=pthread_key_create; lookup in
file=/usr/lib/libXdmcp.so.6 [0]
6922: ./test: error: symbol lookup error: undefined symbol:
pthread_key_create (fatal)
Segmentation fault (core dumped)
I don't know (as of now) how to debug the .init section code of a shared
library, so I'll have to stop here.
