 Optimizations and stripping symbols usually causes this problem. What is
 Pidgin using for crash reporting?

 The only compiler changes are the the additions to `CC_HARDENING_OPTIONS`
 and the linker changes are `LD_HARDENING_OPTIONS` in [d9ebf57cd361].
 The way things are being stripped hasn't changed either.

 We're using a [https://hg.pidgin.im/util/drmingw/ forked version] of the
 drmingw `exchndl.dll` which uses the binutils bfd library to get at the
 debug symbols.

 If there were something better, we'd be happy to use it.
