874	Compiling some files may cause infinite optimization loops, eating all available memory	Mario Domenech Goulart	felix winkelmann	"chicken (master -- e5f341a81cb2d5b8c4f7d8eedabcd35c1ecb7281) dies with a segmentation fault when attempting to compile the attached file (srfi-14-test.scm).

While compiling, it uses more than 2GB of RAM. It crashed after running for more than 9 minutes on a 2.4GHz processor.  The system is Linux x86.

I tried building chicken with DEBUGBUILD=1 and running it under gdb, but it didn't crash in more than 10 hours, when I stopped it (it was still using 2GB of RAM)."	defect	closed	major	4.9.0	compiler	4.7.x	fixed
