[Tinycc-devel] Segfault compiling bash?

[charlesrandall4-tinycc]

I'm new to tcc and am trying to compile a number of
different programs to see how well it would work in
"real life".

Attempting to compile bash-3.0 using tcc 0.9.21 on
RedHat Linux 9 and run into the following problem,

tcc  -DPROGRAM='"bash"' -DCONF_HOSTTYPE='"i686"'
-DCONF_OSTYPE='"linux-gnu"'
-DCONF_MACHTYPE='"i686-pc-linux-gnu"'
-DCONF_VENDOR='"pc"'
-DLOCALEDIR='"/tmp/cfr/share/locale"'
-DPACKAGE='"bash"' -DSHELL -DHAVE_CONFIG_H  -I.  -I.
-I./include -I./lib   -g -c variables.c
variables.c:1981: constant expression expected
make: *** [variables.o] Segmentation fault

If I try to run tcc_g in the debugger the backtrace
is,

Has anyone looked at this?
