Hello!
Please excuse me some formal mistakes, i am not really
familiar with reporting bugs to you :)
The missing package-header in the previous mail
was such one, sorry.
Here's the problem i had on my potato-distribution
with kernel 2.2.18 and netbase-package version 3.18-4.
While i have set MALLOC_CHECK_=2 in my environment,
the rpcgen abort's when creating the xdr-file and the
xdr-File contains a struct where some fields can
be inline'd:
$ uname -a
Linux sapc154 2.2.18 #6 Thu Apr 12 17:05:24 CEST 2001 i686 unknown
$ cat test.x
struct _MYSTRUCT {
long Val1;
long StopReq;
long StopArg;
long StopCountDown;
};
$ export MALLOC_CHECK_=2
$ rpcgen -c test.x
/*
* Please do not edit this file.
.
.
.
}
else {
IXDR_PUT_LONG(buf,objp->Val1);
Aborted
$ unset MALLOC_CHECK_
$ rpcgen -c test.x
/*
* Please do not edit this file.
.
.
.
}
return (TRUE);
}
So i found the source for this in file netkit-base_0.10.orig.tar.gz
at http://ftp.debian.org/debian/pool/main/n/netkit-base/
patched in the file netkit-base_0.10-6.1.diff.gz and debugged rpcgen.
Hope this is the right source.
The problem i found is that in
file rpc_cout.c line 707 should be changed
from
ptr = malloc(strlen(str));
to
ptr = malloc(strlen(str)+1);
Greetings
Michael Haubenwallner
