------- Comment #3 from de at cs dot brown dot edu 2006-09-19 21:49 ------- Subject: Re: internal compiler error at cfgexpand.c:515
It seems to still be a problem with 4.1.1 (released 20060511). Maybe this is a slightly different problem? If not, what version has fixed this? Or, how can I change my code to avoid the stack overflow? Thanks, David /usr/bin/gcc-4.1 -Wall -pedantic -g -c -o desh.o desh.c -v Using built-in specs.
