Subject [Fwd: [mp2] coredump strerror code on Solaris 8
Date Wed, 08 Sep 2004 21:01:33 GMT
Arshavir reports segfaults on Solaris 8 all in the apr land:

Here is one:

#0 0xff2a7fec in apr_cpystrn (dst=0xffbeee90 "яПН\001", src=0x0, dst_size=256)
at apr_cpystrn.c:57
57 if (!(*d = *src)) {
(gdb) where
#0 0xff2a7fec in apr_cpystrn (dst=0xffbeee90 "яПН\001", src=0x0, dst_size=256)
at apr_cpystrn.c:57
#1 0xff2c0f18 in stuffbuffer (buf=0xffbeee90 "яПН\001", bufsize=256, s=0x0)
at errorcodes.c:34
#2 0xff2c18e8 in native_strerror (statcode=-4264304,
buf=0x100 <Address 0x100 out of bounds>, bufsize=0) at errorcodes.c:375

Here is another:

(gdb) bt
#0  apr_cpystrn (dst=0xffbef010 "", src=0x0, dst_size=4290703375)
    at apr_cpystrn.c:57
#1  0xff1d4c4c in stuffbuffer (buf=0xffbeef10 "", bufsize=256, s=0x0)
    at errorcodes.c:34
#2  0xfee074f0 in modperl_error_strerror (rc=500) at modperl_error.c:37
#3  0xfe990c90 in XS_APR__Error_strerror (cv=0x1f4) at Error.xs:36

In the second one the trace seems to be optimized away, since 
modperl_error_strerror does not call stuffbuffer, so it's some internal 
function that is broken.

Anybody has an idea of the cause?
