Abort (core dumped) My scripts run normally until the end and then, the SEGFAULT occurs. This bug occured with the perl 5.8.9 update. Compiling perl and p5-ReadLine-Gnu with debugging did not give me reasonable results. Without debugging, I get: .Assertion failed: ((run->regs_mask[elm] & (1U << bit)) == 0), function arena_run_reg_dalloc, file /usr/src/lib/libc/stdli b/malloc.c, line 2543.
