I'm using make-3.81beta4 on Solaris SunOS 5.9 compiled with Sun cc 5.5. I have a large non-recursive make system which builds around 250 directories of source code. I'm seeing make hang after building roughly half the source. Running up the debugger I see that it's actually going round in circles in the function variable.c:target_environment. This is due to the variable list associated with the target file being circular. The outer loop:
for (s = set_list; s != 0; s = s->next) is non-terminating because at some point s->next is somehow ending up pointing back at a previous member of the list. I'm using the same make system to build the same source tree on Linux (Red Hat enterprise 2.6.9-22.0) using make 3.80 and everything works fine, so this is clearly a platform issue. I'm speculating that the error is due differences in the behaviour of malloc on the two platforms - ie on Solaris malloc is giving back a previously used variable_set_list object with an (accidentally) valid next pointer. But, this is idle speculation. The bug is easily reproducible but only with a large set of makefiles. Is this a known issue? I having found anything in the achieves relating to it. ================================= Atos Euronext Market Solutions Disclaimer ================================= The information contained in this e-mail is confidential and solely for the intended addressee(s).
