[Bug target/37584] -ftree-ch causes stack corruption on mingw32

[dannysmith at users dot sourceforge dot net]

------- Comment #3 from dannysmith at users dot sourceforge dot net  2008-09-22 03:23 -------
I have run into what I believe is the same bug in build of of cc1plus.exe, with
miscompilation of cp/pt.c
When exercising cp/pt.c:process_partial_specialization (eg, when compiling
libstdc++'s mt_allocator.cc) I get a segfault in cygwin.asm (used in w32
implementation  of __builtin_alloca)  
Adding -fno-tree-ch to CFLAGS for pt.c fixes build of libstdc++ and testsuite
results  

I will try to reduce a testcase when time permits.
Danny
