Are mixed debug formats in one exe supported?

I am trying to add DWARF2 support to PE/COFF for Cygwin/Mingw. They
currently use stabs.
While testing, executables end up having mixed stabs/DWARF2 debugging
info if any system/gcc/previously compiled static libs are linked in.
The result causes gdb to SEGV while traversing the partial symbol tables
looking for symbol main.
The problem is that init_psymbol_list is called for the executable twice
due to mainline being set at dbxread.c:562, and again at
dwarf2read.c:1076.
So, the question. Is this meant to work? I assume the reason mainline is
used here is:
/* If we are reinitializing, or if we have never loaded syms yet, init */
Why does reinitializing not clean up after itself (ie. reset the
[global|static]_psymbols.size to 0)? Is that a leak?
I'm going to keep digging, but since I have zero knowledge of gdb
internals, I thought I'd ask and save some time. Thanks.
