I haven't found any reliable documentation about this corner case, but changing the regexp like that fixes the problem here. Another solution would be to force it using gawk, but considering the size of the patch that seems silly to add such a requirement. Please let me know if you want me to send it upstream (and where to send it), but the patch is so trivial that I think it could be sent with other ones. vapier@gentoo.org 2007-12-22 07:44:52 0000 while i consider the syntax used here pretty useful, i think it's a violation of POSIX ... please refer to: http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html 9.4.3 ERE Special Characters The vertical-line is special except when used in a bracket expression (see RE Bracket Expression). A vertical-line appearing first or last in an ERE, or immediately following a vertical-line or a left-parenthesis, or immediately preceding a right-parenthesis, produces undefined results. my interpretation of this is that "(|DEF)" is invalid anyone else feel like reading that and confirming ? vapier@gentoo.org 2007-12-24 19:15:46 0000 thinking about it, these two should be completely interchangeable: moo(|cow) moo(cow)? so i'll patch it to do the latter vapier@gentoo.org 2007-12-24 19:25:40 0000 added to current glibc-2.7-r1 ebuild http://sources.gentoo.org/gentoo/src/patchsets/glibc/2.7/1050_all_glibc-posix-awk.patch?rev=1.1 139031 2007-12-21 11:00 0000 proposed patch glibc27_please_bsd_awk.patch text/plain LS0tIGdsaWJjLTIuNy9lbGYvTWFrZWZpbGUub2xkCTIwMDctMTItMjAgMjM6Mzc6MTYgKzAwMDAK KysrIGdsaWJjLTIuNy9lbGYvTWFrZWZpbGUJMjAwNy0xMi0yMCAyMzozNzozMyArMDAwMApAQCAt MzE1LDcgKzMxNSw3IEBACiAJCSAgLVdsLC1zb25hbWU9JChydGxkLWluc3RhbGxlZC1uYW1lKSAt VCAkQC5sZHMKIAlybSAtZiAkQC5sZHMKIAlyZWFkZWxmIC1zICRAIFwKLQkgIHwgYXdrICcoJCQ3 IH4gL15VTkQofEVGKSQkLyAmJiAkJDEgIT0gIjA6IiAmJiAkJDQgIT0gIlJFR0lTVEVSIikgeyBw cmludDsgcD0xIH0gRU5EIHsgZXhpdCBwICE9IDAgfScKKwkgIHwgYXdrICcoJCQ3IH4gL14oVU5E fFVOREVGKSQkLyAmJiAkJDEgIT0gIjA6IiAmJiAkJDQgIT0gIlJFR0lTVEVSIikgeyBwcmludDsg cD0xIH0gRU5EIHsgZXhpdCBwICE9IDAgfScKIAogIyBpbnRlcnAuYyBleGlzdHMganVzdCB0byBn ZXQgdGhpcyBzdHJpbmcgaW50byB0aGUgbGlicmFyaWVzLgogQ0ZMQUdTLWludGVycC5jID0gLUQn UlVOVElNRV9MSU5LRVI9IiQoc2xpYmRpcikvJChydGxkLWluc3RhbGxlZC1uYW1lKSInIFwK
