It works as expected with upcoming gcc-2.95, so it appears that the
bug has been fixed.

Thanks for your bug report. I could reproduce it with egcs
1.1. gcc-2.95 19990701 says

a.cc:2: in-class initialization of static data member of non-integral type `const string'

so it appears that the bug is fixed.

Martin

Upcoming gcc-2.95 isses the following diagnostic:
 
 $ gcc --version
 2.95
 $ gcc -Wall -ansi -pedantic x1.cc 
 x1.cc:2: in-class initialization of static data member of 
   non-integral type `const string'

Looks like the bug has been fixed for 2.95.

Thanks.  Please note that you got warnings, not errors.  In any case,
GCC has undergone a major warning clean-up, thanks mostly to Kaveh
R. Ghazi, so it is possible that, in the development tree, most or all
of these warnings are no longer present.  Would you like to give it a
try and report back if you still find them?

Thanks for your bug report.  The latest development snapshot of gcc
compiles it successfully, but it is unlikely that the bug will be
fixed in the 2.95.* series.  You'll have to compile this particular
file without -DNDEBUG on alpha, before gcc 2.96 is released.

I cannot reproduce this with gcc-2.95 on x86-linux, and interestingly
enough, nor with egcs-1.1.2 on x86-linux.

This appears to be an ev56 specific code generation problem.

Compiling for an ev56 we get the following sequence for the conversion from
FP to an int type:

0x120001194 <MAIN__+148>:       cvttq/c $f10,$f10
0x120001198 <MAIN__+152>:       sts     $f10,68(sp)
0x12000119c <MAIN__+156>:       nop
0x1200011a0 <MAIN__+160>:       ldl     t0,68(sp)
0x1200011a4 <MAIN__+164>:       mov     s2,a0
(gdb) display/i $pc
1: x/i $pc  0x120001194 <MAIN__+148>:   cvttq/c $f10,$f10
(gdb) p $f10
$1 = 91.5
(gdb) stepi
0x120001198 in MAIN__ ()
1: x/i $pc  0x120001198 <MAIN__+152>:   sts     $f10,68(sp)
(gdb) i r $f10
f10            4.4959973771553436e-322  (raw 0x000000000000005b)
(gdb) stepi
0x12000119c in MAIN__ ()
1: x/i $pc  0x12000119c <MAIN__+156>:   nop
(gdb) 
0x1200011a0 in MAIN__ ()
1: x/i $pc  0x1200011a0 <MAIN__+160>:   ldl     t0,68(sp)
(gdb) 
0x1200011a4 in MAIN__ ()
1: x/i $pc  0x1200011a4 <MAIN__+164>:   mov     s2,a0
(gdb) p/x $t0
$2 = 0x0

Note how $f10 has the right value, but the value we load out of the stack
is totally bogus, presumably because we did not store the right value into
the stack.

Richard, you'll need to take over at this point.

Note, if you compile for an ev6 the code uses ftoit which seems to avoid this
problem.
