Re: pkg/54348: pkgsrc net/fetch core dumps

[Hiroshi Hakoyama <hiroshi-hakoyama%nagano.ac.jp@localhost>]

Dear coypu,

I found that OpenCSW provides gcc 5.5 for Solaris 10. 
I installed gcc 5.5 (csw) instead of gcc 4.9.4 (pkgsrc) as a pkgsrc compiler; As I reported in previous reports, devel/gdb and lang/gcc5 in pkgsrc fail to build on Solaris 10. 
I built libfetch and fetch with CFLAGS+= -g -O0 and INSTALL_UNSTRIPPED=yes in mk.conf.

The /opt/csw/bin/gdb seems to be functional in this case. Please find the following output.
