hi,
as $subject says. i have bisected the problem to have been introduced
in r12466 (r12465 is fine).
r12466 only says segmentation fault, leaving an empty hb_out.log;
r14542 is a bit more verbose with:
Application Internal Error -
/home/ice/w/xhb/hbci/harbour-bisect/harbour/inst/linux/sunpro/c/bin/hbrun
Terminated at: 2010.05.20 22:26:52
Unrecoverable error 6005: Exception SIGSEGV at address 0x1b800ad5268
Called from GET(73)
Called from GETNEW(1978)
Called from __GET(70)
Called from HB_DOTPROMPT(162) in ../../../hbrun.prg
Called from _APPMAIN(124) in ../../../hbrun.prg
------------------------------------------------------------------------
(backtraces for both cases are below).
this only happens if hbrun is requested to run interactively (eg.
using the dot console); if it is to run a program (at least a simple
one), it's ok. i also have not been able to find anything similar with
the other compilers i'm testing with.
build environment is ubuntu 10.04/x64 and ubuntu 6.06/i386, with the
following settings:
unset ${!HB_*}
export HB_BUILD_DEBUG=yes
export HB_COMMERCE=yes
export HB_BUILD_OPTIM=no
export HB_CONTRIBLIBS=no
export HB_WITH_PCRE=yes
export HB_WITH_ZLIB=yes
export HB_PLATFORM=linux
export HB_COMPILER=sunpro
export HB_BUILD_MODE=cpp
export HB_INSTALL_PREFIX=$appdir/inst/$HB_PLATFORM/$HB_COMPILER/$HB_BUILD_MODE
(HB_WITH_PCRE and HB_WITH_ZLIB are not present when building head)
sunpro is cc: Sun C 5.10 Linux_i386 2009/06/03 (CC doesn't work for a
while, barfing on some system headers).
here's what gdb has to say about this (this particular one being
ubuntu 10.04/x64; 6.06/i386 is essentially the same, save for the
addresses):
this is the backtrace for r12466, where the problem originally was
introduced:
