   Hello Maurice!

29 Aug 17 22:13, you wrote to me:

Yes, I used those as well. That's what you get when you run apt-get source 
ifmail.
First I then ran a dpkg-buildpackage -uc -us, which will result in a local 
rebuild of that Debian package, including all Debian patches.
But this segfaults as well, so I tried to build just from orig.tar.gz without 
Debian patches, because I was asked for "compiling the (upstream) source". It 
doesn't build that way without major quirks.

From Debian package:
# ldd /usr/lib/ifmail/ifcico
        linux-vdso.so.1 (0x00007ffd423bb000)
        libgdbm_compat.so.3 => /usr/lib/x86_64-linux-gnu/libgdbm_compat.so.3 
(0x00007fc17b9c1000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc17b622000)
        libgdbm.so.3 => /usr/lib/x86_64-linux-gnu/libgdbm.so.3 
(0x00007fc17b41b000)
        /lib64/ld-linux-x86-64.so.2 (0x000055d30e603000)

libfl and libm are missing. For libfl I can install libfl-dev and libm.so.6 
should already be available, because it's within libc6 package:

libc6: /lib/x86_64-linux-gnu/libm.so.6
libfl-dev: /usr/lib/x86_64-linux-gnu/libfl.so.2

But libfl-dev is already installed:
libfl-dev is already the newest version (2.6.1-1.3)

I want to run my modem line with an EMSI compatible mailer, just because I like 
that connecting sound of a modem for some strange reasons. ;)

As stated above that's the Debian package version I already built myself and it 
segfaults, too. The version is also listed in Debians bug report: 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=872507

I've put the build log to https://paste.debian.net/hidden/f86ee0f1/ - it still 
segfaults:

~/temp/ifmail-2.14tx8.10# ifcico/ifcico
Segmentation fault
