In fact, I tried +RTS -DS before posting this report but that didn't make any differences. (-DS needs -debug rts and it behaves just like the normal -debug rts; the SEGV.) Btw, I found the problem didn't occur at all on the current darcs HEAD. I'll try to find the testsuite that fails when I stumble on it again. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/4034#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Also try the sanity checker (+RTS -DS). It will make things easier if you find a smaller program from the testsuite that fails, rather than GHC itself. I'd like to point out that it's not unknown for GCC to have bugs - we've had to work around them in the past, e.g. look in `LdvProfile.c`. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/4034#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Comment(by PHO):
I found I can avoid the problem by putting the following options to
mk/build.mk:
{{{
GhcRtsHcOpts = -optc-O0 -optc-g
GhcRtsCcOpts = -O0 -g
}}}
This is my observation so far:
* Optimized libHSrts_thr.a causes an evacuate() error.
* libHSrts_debug.a causes a segmentation fault.
* Unoptimized libHSrts_thr.a looks working.
...so the problem is not likely in gcc's optimizer but in rts. GCC is just
revealing the hidden rts bug.

Comment(by PHO):
Here is the assembly code that caused a SegFault:
{{{
0x012a42c4 s1ht_info+0: lis r31,298
0x012a42c8 s1ht_info+4: addir31,r31,16880

0x012a42d8 s1ht_info+20: bne-0x12a42e8 s1ht_info+36
0x012a42dc s1ht_info+24: lwz r31,0(r14) ; CRASHES HERE

0x012a42ec s1ht_info+40: .long 0xc
}}}
SegFault occurs at s1ht_info+24 trying to load a word pointed by r14 (STG
R1 register) but the value of r14 is zero.
The corresponding C-- code is:
{{{
s1ht_ret()
{ has static closure: False update_frame: none

desc: 0
tag: 34
stack: [Nothing]
srt: (ghczm6zi12zi2_UniqFM_lookUp_srt,0,1)
}
c1Mq:
I32[Sp + 0] = s1wl_info;
if (R1 3 != 0) goto c1Mt;
jump I32[R1] (); /* CRASHES HERE */
c1Mt: jump s1wl_info ();
}
}}}
