Comment 17 for bug 836588

I hit this with Linaro GCC 4.6 (4.6.1-based) and the same pkeyparam.c from OpenSSL. I am also compiling with -Os and -fPIC, and implicitly with -mthumb (the default in my toolchain); so it's not specific to ARM mode.

The situation appears to be that two pc-relative fetches (artifacts of -fPIC and string literals) get folded together, losing one of the labels (needed for calculation of the offset in the table of PIC indirections).

Reverting http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=163998 makes the problem go away, at least at compile time; I should be able to run a test suite soon.
