It works without -O. I'm on stock Mandrake 9.0 system.

It appears that the version of GCC 3.2 supplied with Mandrake 9.0 ignores the -fomit-frame-pointer flag, and this confuses GHC's mangler. The version of GCC supplied with RedHat 8.0 (gcc version 3.2 20020903) does not seem to have this problem...

Upgrading from the Mandrake 9.0 default gcc-3.2-1mdk to gcc-3.2-4mdk from Mandrake cooker appears to solve the problem.
