When objects have been built with gcc's "-fasynchronous-unwind-tables" option,
linking them can produce a segfault in ld. This occurred when trying to build a
recent Linux kernel with frame unwinding information. I've narrowed it down to
a simpler test case, which uses the kernel's link script and a couple of test C
files. Enabling "-fasynchronous-unwind-tables" when building the objects causes
a subsequent link to crash ld, while disabling that option causes ld to continue
successfully (giving the user an error and then exiting).
ARM EABI toolchain: binutils 2.17, gcc 4.1.1, built with CrossTool 0.42
Also tried CodeSourcery's 2006q1-6 toolchain (uses binutils 2.16.91), which
experiences the same problem
Will follow up with test files
