System: Linux hector.lesours 2.2.19 #2-Reiser Thu Aug 30 22:14:16 CEST 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: /usr/src/Lang/gcc-3.0.1/configure --verbose --disable-shared
>Description:
the following simple code produces following GCC abort when compiled with -fvolatile -O flags
genkoba.c: In function `second':
genkoba.c:56: Internal compiler error in fixup_var_refs_1, at function.c:1922
Please submit a full bug report,
The system is a Linux Debian/Sid, gcc being the 3.0.1 release (compiled by me) installed in /usr/local/bin/gcc
for your information
here is the (simple) source code -which generated a simplistic C header file using a line of stars as separator
the genkoba.c file has 56 lines and its md5sum is 27bc1f42742db1faf79f9521ae981a7e

*****************************************************************************************
the GCC bug appears with the -fvolatile flags and the -O or -02 or -02 optimisation.
removing either the -fvolatile flag or the optimisation flags avoids the GCC bug
>Fix:
I am coding a copying garbage collector (in a GPL-ed free software) which requires -fvolatile
I do not know about any fixes
Kind regards
