Hello,
Your logs show that there is a memory layout conflict in sbcl:

And then sbcl does an allocation of the linkage tables from 0xf800000 upto 0x10000000. This goes right over where the libraries are in memory:
src/compiler/sparc/parms.lisp ... (def!constant linkage-table-space-start #x0f800000) (def!constant linkage-table-space-end #x10000000)
and in the strace:
mmap(0xf800000, 8388608, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0) = 0xf800000
A while later it crashes. To fix this one would need access to a sparc64 machine to further debug this problem, but vore is still down so I cannot use a debian machine to investigate this.
Hi Peter, if yo want i could try to put up a sparc64 wit Debian on it and attac it to the net. Cheers, RalfD
If you can recompile sbcl you could try to change the parms.lisp file move the LT to some other place. Maybe #xa0000000 to #xa0800000?
Groetjes, Peter
