tags 377630 + patch upstream kthxbye The problem here is an extra semicolon. The semicolon at the end of line 55 makes i==MAXSIG. Then, on line 56, signames[MAXSIG] is set to zero, which causes a segfault. That this only happens on powerpc is probably due to a code size fluke or something similar; regardless, the code is invalid on all platforms.
A patch is attached to fix this problem. I tagged the bug "upstream" because in all likelihood, this is an upstream problem as well. It may also occur in programs derived from ircii; these should be easy to spot, since there's a set of security bugs going around right now. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 713 440 7475 | http://crustytoothpaste.ath.cx/~bmc | My opinion only OpenPGP: RSA v4 4096b 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
