[Help-smalltalk] [2.0.7] on sparc

[Nicolas Pelletier]

Hello,

I am  having trouble with  'make check' on  sparc with gst  2.0.7.

uname -m = sun4u
uname -r = 5.6
uname -s = SunOS
uname -v = Generic_105181-23

I am using gcc 2.95.2. I applied the following patch to gst sources:

http://mail.gnu.org/pipermail/help-smalltalk/2002-September/000408.html

and edited the Makefiles to switch optimization to -O. I am building a
traditional interpreter (no jit). During make check, 1 test fails (all
other are ok :-) ):

IntegerANSITest>>testXasFloatQ ..
Program received signal SIGSEGV, Segmentation fault.
0xef51d168 in .stret8 () from /usr/lib/libc.so.1

The backtrace is:

(gdb) print *mpz->d
$3 = 2000000000

Stripping   IntegerANSITest>>testXasFloatQ  down   to   the  following
triggers the  error. The  lines testing  2, -2 and  0 in  the original
version of the test pass without problems.

testXasFloatQ
        " <number>#asFloatQ "
        #'Numeric'.
        self value: [-2000000000 asFloatQ] should: [:r | r = -2000000000.0]
                conformTo: #'number' selector: #'asFloatQ'.!

The libc I  am using does not have ldexpl and  friends: they come from
gst. What causes this problem ? Thanks in advance for any help.
