The simplest method is just to tweak the linker script to make .rdata
writable (or rather, to map both .data and .rdata input segments into
the same .data output section.)
There is no method that I'm aware of to find the name of the offending
symbol. Actually, that's not quite true, see
<http://cygwin.com/ml/cygwin-patches/2008-q1/msg00067.html>. As I said
in that message though, those might just be coindicental and certainly
not guaranteed across OS versions or whatever.

strace under Cygwin is not like strace on other operating systems, it is
really just a glorified viewer for a bunch of debug_printf statements
that exist in the Cygwin code. The error occurs before the process even
begins execution, during the period where NTLDR loads libraries into its
address space. So, strace will be of no use.
