Pre-processed failing source
When building Mozilla Firefox with LTO (gcc revision 196427, FF
changeset 123831:c95439870e05), I'm encountering an ICE when compiling
js/src/ion/shared/CodeGenerator-shared.cpp (and I suppose the same one
in a number of other files). The problem occurs in the compilation
phase.
The ICE simply disappears when I add -save-temps to the command line
but reappeared when I also added --param ggc-min-expand=10 --param
ggc-min-heapsize=1024. The attached resultant .ii file also ICEs but
--param ggc-min-expand=5 --param ggc-min-heapsize=512 is necessary to
trigger it.
