[Ecls-list] sig11 in cl_boot()

[Stanislaw Halik]

Heya,

After linking ECL with a certain C program, it crashes in cl_boot().

Backtrace follows:

Strangely enough, the call to cl_boot() is the first statement in the
program's main.

My system is an x86 running Linux 2.6. cl_boot() crashes with the same
backtrace with both ECL 0.9i and latest CVS.

Changing the optimization level (from -O to -O0 or `-O2
-fno-strict-aliasing') of the program doesn't help. Same goes for static
vs dynamic linking of libecl.

I thought that some library might be in conflict with ECL, but linking a
test program with the same libraries doesn't make it crash.

Frame #13, ecl_init2() can be something as simple as:

        char *argv[] = {"ecl", 0};
        cl_boot(1, argv);

Any hints? I'm out of luck :(
