There were a few references here (I remember a few, eg., the one from
Mark Salazar), but mostly directly to me via private email. I have about
25 messages in my queue with various testcases that show this same bug.

You're right about the mysterious .text (which is really the output from
readonly_data_section, which for x86-win32 is .text, not .rdata yet), and
I just figure out why the C front end insists on doing this.

If I knew how to fix it, it would be fixed by now ;-) I've been ignoring
this since there is a easy workaround (and easy to spot, since your
program simply crashes), but it's in the egcs-bugs list and will get
looked at eventually.
For help on using this list (especially unsubscribing), send a message to
"email@example.com" with one line of text: "help".
