Comment (by SimonKing):
What I did to produce a singular spkg that produces a malloc-libsingular:
* Drop attachment:sage_trac_13731.patch into the spkg's `patches/`
directory
* Apply the following change to spkg-install:
{{{
#!patch
diff --git a/spkg-install b/spkg-install
--- a/spkg-install
+++ b/spkg-install
@@ -134,6 +134,7 @@
--libdir="$SAGE_LOCAL"/lib \
--with-apint=gmp \
--with-malloc=system \
+ --with-emulate-omalloc \
--with-NTL \
--without-MP \
--without-lex \
}}}
With that, I seem to get a working libsingular, and I get the due segfault
with `export MALLOC_CHECK_=3` in the example of the ticket description.
However, I do not obtain a working Singular executable.
I am now testing whether the spkg works on bsd.math as well.
