Bug#458072: cpp-4.1: segmentation fault in cc1 due to infinite loop in error() when using -ftrapv
Package: cpp-4.1
Version: 4.1.1-21
Severity: normal
I get the following segmentation fault:
courge:...re/mpfr-2.3.1-rc1> gcc -DWANT_ASSERT=2 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DTIME_WITH_SYS_TIME=1 -DHAVE_STDARG=1 -DHAVE_SYS_TIME_H=1 -DHAVE_SETLOCALE=1 -DHAVE_GETTIMEOFDAY=1 -DMPFR_HAVE_FESETROUND=1 -DHAVE_DENORMS=1 -DHAVE_FLOOR=1 -DHAVE_CEIL=1 -DHAVE_LDOUBLE_IEEE_EXT_LITTLE=1 -DHAVE_ATTRIBUTE_MODE=1 -DHAVE_ALLOCA_H=1 -I. -I. -I/home/vlefevre/x86_64/gmp-debug/include -Wall -Wmissing-prototypes -g -O2 -ftrapv -MT print_raw.lo -MD -MP -MF .deps/print_raw.Tpo -c print_raw.c -fPIC -DPIC -o .libs/print_raw.o
gcc.real: Internal error: Segmentation fault (program cc1)
Note: the print_raw.c file has not changed since MPFR 2.3.0, but
I haven't tried yet to reproduce the bug when compiling MPFR 2.3.0.
The crash doesn't occur without -ftrapv.
