Seen it now. The offending line was:
#define PATH_VARIABLE_NAME "TTSDATA"
[...]
strcpy(task_filename, getenv(PATH_VARIABLE_NAME));
On his Sun system, the environment variable TTSDATA is defined, on his
linux box, it is not :)
That's where it segfaults. getenv returns NULL and the first strlen()
in strcpy() dumps core.
So it's not a Sun/Linux thing, it's an environment thing :)
