[Coin-discuss] make test segfaults on trunk of cbc on solaris with solaris c/cpp compilers

[Sven de Vries]

hi,

i just updated my local trunk version of cbc .

here is part of my environment:

uname -m = sun4u
uname -r = 5.8
uname -s = SunOS
uname -v = Generic_117350-31

/usr/bin/uname -p = sparc
/bin/uname -X     = System = SunOS
Release = 5.8
KernelID = Generic_117350-31
Machine = sun4u
BusType = <unknown>
Serial = <unknown>
Users = <unknown>
OEM# = 0
Origin# = 1


...
configure:2949: C compiler options are: -xO4  -DNDEBUG
configure:3078: checking for CC
configure:3094: found /opt/SUNWspro/bin/CC

cc: Sun C 5.8 2005/10/13
CC: Sun C++ 5.8 2005/10/13


doing a make distclean, configure,  make and make test results in:

segfault while doing bell5 and starting blend2:
FlowCover was tried 1 times and created 0 cuts of which 0 were active 
after adding rounds of cuts ( 0 seconds)
TwoMirCuts was tried 64 times and created 161 cuts of which 2 were active 
after adding rounds of cuts ( 0.05 seconds)
cbc_clp 8.96641e+06 = 8.96641e+06 ; okay - took 107.23 seconds.

(details follow below.)

just wanted to let you know.
