[sean@vela tmp]$ file musca
musca: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, stripped
Would you mind rebuilding with symbols unstripped (we compile with gcc -g by default), and capture the core again with this new binary, please? No symbols makes it hard to dig around with gdb. Attach new core and binary as before.
If this is a segfault occuring as a result of us not checking EINTR (error 4) correctly somewhere, then you can also try adding the following line to the top of musca.c:
#define _GNU_SOURCE
This should make the default EINTR behavior be to retry the interrupted system call. However, since this might be a heisenbug, only make this change *after* you've triggered the fault at least once with the new binary.
