[Bug middle-end/41343] New: sysdeps/ieee754/dbl-64/dosincos.c from glibc causes excessive memory use

["froydnj at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When compiling the attached file as:

powerpc-linux-gnu-gcc dosincos.i -g -O2 -std=gnu99 -fgnu89-inline
-fmerge-all-constants

The memory use of GCC balloons to 4GB+.  I have a low ulimit on my machine, so
I don't know whether leaving it alone with more memory would let the
compilation finish.  Using -fdump-tree-all-details indicates that things die
somewhere in the inline_param3 pass.

Discussion on IRC demonstrates the same behavior with a cross compiler from
x86-64, with memory usage up to 12GB without finishing.
