[users@httpd] Problems with Apache 1.3.31 on 64bit Linux platform
Hi all,
this is a REPOST as nobody even acknowledge my first post (Aug 26th).
On 64bit (AMD Athlon64 for now) I've detected weird problems with
LocationMatch. I traced the problems to HS regex library (bundled with
Apache 1.3). The regex test script in the apache_1.3.31/src/regex
directory give this:
./re <tests
Segmentation fault
./re -x <tests
....
314:
Segmentation fault
I'll be happy to give more details and run some tests if necessary.
Regards,
Gabriel

Hi,
I guess this is what you asked for:
test regex $ ./re <tests
Segmentation fault (core dumped)
test regex $ gdb ./re core
