located segfault, Embperl 2.0b7 Solaris 2.8, epmain.c
Compiling and testing Embperl 2.0b7 on Solaris 2.8, gcc 2.95.3, without
mod_perl or XML libs, produces segfault on "make test". The segfault can be
corrected, and the test script then runs perfectly, by commenting out line
596 of epmain.c :
lprintf (r -> pApp, "[%d]PERF: input = %s\n", r -> pThread -> nPid,
sInputfile) ;
In this line, the parameter 'sInputfile' is null, and causes a segfault as
follows:
#0 0xff1b3084 in strlen () from /usr/lib/libc.so.1
#1 0xff202c58 in _doprnt () from /usr/lib/libc.so.1

Yes, this is a "feature" of solaris clib. All other OS I know will display
<null> instead of segfaulting...
I have already found this bug and corrected it in my developement version.
Anyway thanks for the hint
