Re: [Gcl-devel] building gcl-2.6.12: raw_gcl segfaults

Greetings!  In the failing environment, there is apparently some wrapper
to open() which is interfering with a read of /proc/meminfo:

17104 brk(0x800d12000)  = 0x800d12000
17104 brk(0x800d16000)  = 0x800d16000
17104 brk(0x800d18000)  = 0x800d18000
17104 brk(0xd1b000) = 0xd1b000
17104 open("/proc/meminfo", O_RDONLY)   = 3
17104 read(3, "MemTotal:8074492 kB\nMemF"..., 4096) = 1011
17104 close(3)  = 0
17104 brk(0xcd9e3000)   = 0xcd9e3000
17104 stat("/proc/17104/exe", {st_mode=S_IFREG|0755, st_size=4446024, ...}) = 0

vs

This method of determining the runtime available memory has been
replaced in 2.6.13pre with (hopefully) more robust alternatives.  But
hopefully this should point out what is going on.

Please let me know what you find out and we might make an FAQ or
something. 

Take care,

I've edited unixport/makefile to run raw_gcl under strace -f. The trace 
when raw_gcl is invoked by make and fails is short, it's 
gcl_fail.strace.bz2. The trace when I invoke raw_gcl from the command line 
is much longer: gcl_succ.strace.bz2.


Thank you for your patience,

2016-10-17 Thread Andrey G. Grozin 
Something really strange is happening (absolutely reproducibly). I cannot 
understand.


After this failure in the build process, make removes raw_gcl. This is 
inconvenient for debugging. Therefore I removed it from .INTERMEDIATE in 
the makefile in unixport. I run make in the toplevel directpry, and get


/var/tmp/portage/dev-lisp/gcl-2.6.12/work/gcl/unixport/raw_gcl 
/var/tmp/portage/dev-lisp/gcl-2.6.12/work/gcl/unixport/ -libdir 
/var/tmp/portage/dev-lisp/gcl-2.6.12/work/gcl/ < foo


Unrecoverable error: Segmentation violation..

(the first 3 lines here are, of course, 1 line split by the email client). 
But now raw_gcl is still here. So, I run by hand


/var/tmp/portage/dev-lisp/gcl-2.6.12/work/gcl/unixport/raw_gcl 
/var/tmp/portage/dev-lisp/gcl-2.6.12/work/gcl/unixport/ -libdir 
/var/tmp/portage/dev-lisp/gcl-2.6.12/work/gcl/ < foo


(the same 1 line). And it succeeds and produces saved_gcl!

Why does this line fail when started by make, but succeeds when started 
from the command line??
