Note that the signal number listed for for RTMIN is "-1" : 

sig_name_init='"ZERO", "HUP", "INT", "QUIT", "ILL", "TRAP", "ABRT", "BUS", "FPE", "KILL", "USR1", "SEGV", "USR2", "PIPE", "ALRM", "TERM", "STKFLT", "CHLD", "CONT", "STOP", "TSTP", "TTIN", "TTOU", "URG", "XCPU", "XFSZ", "VTALRM", "PROF", "WINCH", "IO", "PWR", "SYS", "NUM32", "NUM33", "NUM34", "NUM35", "NUM36", "NUM37", "NUM38", "NUM39", "NUM40", "NUM41", "NUM42", "NUM43", "NUM44", "NUM45", "NUM46", "NUM47", "NUM48", "NUM49", "NUM50", "NUM51", "NUM52", "NUM53", "NUM54", "NUM55", "NUM56", "NUM57", "NUM58", "NUM59", "NUM60", "NUM61", "NUM62", "NUM63", "RTMIN", "IOT", "CLD", "POLL", "UNUSED", 0'
sig_num_init='0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, -1, 6, 17, 29, 31, 0'

That's strange. What does your signal.h say about it ? (it maybe a file asm/signal.h or
another sig*.h under /usr/include). There's possibly a bug in the Configure script if
your signal number is different from -1.

Anyway, perl should't dump core when given a signal number of -1.
(for reference the core dump is produced by
	$ perl -e '$SIG{RTMIN} = "DEFAULT"'
)
