Re: DDD 3.3.10 (sparc-sun-solaris2.8) gets `Abort' signal

[Arnaud Desitter]

Hi Ludger,

Your compiler is old and not conformant. You should either get the most
recent Sun compiler, apply a Sun patch or use the most recent gcc.

As well, please provide a patch (using diff -u oldfile newfile). But, then,
ddd builds fine with a recent C++ compiler.

Regards,

Subject: DDD 3.3.10 (sparc-sun-solaris2.8) gets `Abort' signal


Hello,

while compiling the DDD Project i got compiler errors in cases when using
the "?:"-operator with a combination of string and non-string objects like 
"".

After i made the beyond mentioned changes, the project compiles 
successfully.
But after the command

$make check

or after simple calling ddd, i get an assertion-abort.
