My m32c-elf newlib builds are crashing at that assert, on an amd64
linux host.
[ gdb ] p *s
$4 = {
str = 0xa6b5a0 "_next",
refcount = 2,
form = 0,
label = 0x0
}
[ gdb ] p *(struct indirect_string_node *)slot
$5 = {
str = 0x2a9565e5c0 "?µ¦",
refcount = 0,
form = 0,
label = 0x0
}
[ gdb ] p slot
$6 = (void **) 0x2a9570acd8
[ gdb ] p *slot
$7 = (void *) 0x2a9565e5c0
The failed file was strtod.c, with this command:
./cc1 -fpreprocessed strtod.i -quiet -dumpbase strtod.c -mcpu=m32cm \
-auxbase-strip lib_a-strtod.o -g -Os -O2 -O2 -version -fno-builtin -o \
strtod.s
This was building as of the 12th.
