Re: [Valgrind-users] Facing issue with valgrind on Solaris x86

You should not need to build 32-bit Valgrind explicitly.
By default Valgrind on newer Solaris should handle both 32-bit and
64-bit programs; but see README.solaris for caveats.
You did not specify Solaris version (pkg info entire) so it is hard to
say where you are.
Note that Solaris 11.1 and 11.2 are quite old now.
You need to compile Valgrind from sources
(http://valgrind.org/downloads/repository.html)
and see if the problem still persists.
If it does, try to do something along these lines and analyze+report the output:
$ dwarfdump -i  /lib/ld.so.1
-or-
$ readelf --debug-dump=info /lib/ld.so.1

Also try to invoke Valgrind with "--read-var-info=yes" to see if this
triggers the problem.

As per "how do I fix this":
1. Analyze and understand the problem.
2. Decide cons and pros of possible solutions.
3. Implement the fix.

I.
