build failure between 108150 and 108164

[Geoff Keating]

Hi Richard,

The trunk now builds, but many PCH tests are failing.  For instance,  
gcc.dg/pch/decl-1.c crashes here:

#0  0x90003008 in strlen ()
#1  0x9000d830 in __vfprintf$LDBL128 ()
#2  0x900ff038 in vfprintf_l$LDBL128 ()
#3  0x90101768 in fprintf$LDBL128 ()
#4  0x001721f0 in switch_to_section (new_section=0x41e11df0) at / 
Network/Servers/hills/Volumes/capanna/gkeating/co/gcc-trunk/gcc/ 
varasm.c:5616
#5  0x0008cecc in machopic_output_indirection (slot=0xa5a5a5a5,  
data=0xa000e790) at /Network/Servers/hills/Volumes/capanna/gkeating/ 
co/gcc-trunk/gcc/config/darwin.c:982
#6  0x004d3874 in htab_traverse_noresize (htab=0xa5a5a5a5,  
callback=0x8cc70 <machopic_output_indirection>, info=0xa000e790) at / 
Network/Servers/hills/Volumes/capanna/gkeating/co/gcc-trunk/libiberty/ 
hashtab.c:729
#7  0x0008cbf4 in darwin_file_end () at /Network/Servers/hills/ 
Volumes/capanna/gkeating/co/gcc-trunk/gcc/config/darwin.c:1445

(Not all of the variable values in the backtrace are correct.)

It looks like section variables, like  
"*machopic_nl_symbol_ptr_section", are being allocated with gcc_alloc  
but their roots are not being marked.
