Hi.
I found tcc segfaults when trying to "-run" pthread-based
C script on Debian (sid, i386) platform, but can compile and
generate correct executable. Following is an example of such
script:
#!/usr/bin/tcc -run -lpthread
int main() { return 0; }
It does not matter what code you have in a script - it's what
you link that seems to matter. In above case, it's libpthread
that triggers SEGV error (in __pthread_initialize_minimal).
After some investigation, the cause was TLS (Thread Local Storage)
feature enabled in glibc. The problem disappears when I do
mv /lib/tls /lib/tls.disabled
Is this a known issue? I searched through the list archive with
various related keywords, but was unable to find such a report.
I still have no idea why tcc fails to run script in-place while
it can generate correct executable without "-run" option.
Is there any workaround to this problem, other than disabling TLS?
Thanks in advance.
