When building on FreeBSD 7.0 or 7.1, the build is interrupted with Illegal Instruction if --enable-pthread is set (with or without --no-tmalloc). I use the following command for repeated tests:

------- 8< ------ 8< ------

make -C source distclean; CFLAGS="-I/usr/local/include" LDFLAGS="-L/

usr/local/lib" ./installer -c --enable-pthread -a /opt/ruby- enterprise-1.8.7-20090928 --no-tcmalloc ------- 8< ------ 8< ------

everything goes fine until miniruby's ready:

------- 8< ------ 8< ------ ... gcc -g -Os -fno-stack-protector -I/usr/local/include -DRUBY_EXPORT - L. -L/usr/local/lib -rdynamic main.o libruby-static.a -Wl,-rpath,/ opt/ruby-enterprise-1.8.7-20090928/lib -L/opt/ruby- enterprise-1.8.7-20090928/lib -lpthread -lrt -lcrypt -lm -o miniruby Illegal instruction (core dumped) * Error code 132 ------- 8< ------ 8< ------

While it's not shown, this Illegal Instruction is for miniruby's first call:

------- 8< ------ 8< ------

I think this should be fixed now. Please feel free to reopen if it isn't.

I'm afraid it's still happening to me. Miniruby compilation is still dumping a core. I've attached my gdb output using the same commands as the original filer used, since I don't know how to use gdb.

It's happening using the installer and using the manual instructions as well.

Still has this issue with version 1.8.7-2011.03 on FreeBSD 6.2 i386.

gcc -g -O2 -DRUBY_EXPORT -L. -rdynamic main.o libruby-static.a -L/opt/local/lib -Wl,-rpath,/usr/local/opt/ruby-enterprise-1.8.7-2011.03/lib -L/usr/local/opt/ruby-enterprise-1.8.7-2011.03/lib -lpthread -lcrypt -lm -o miniruby Illegal instruction (core dumped) * Error code 132

Stop in /root/build/ruby-enterprise-1.8.7-2011.03/source.

This is happening to me on FreeBSD 7.3 i386 even with --no-tcmalloc using 2011.03

This problem is happening to me also on FreeBSD 6.2 (a Verio VPS) with version 1.8.7-2011.03
