Subject: [PATCH] fix "svnadmin create" fail on x86
|
|
|
|
When run the following command on x86:
|
|
|
|
svnadmin create /var/test_repo
|
|
|
|
It cause segmentation fault error like the following:
|
|
|
|
[16499.751837] svnadmin[21117]: segfault at 83 ip 00000000f74bf7f6 sp 00000000ffdd9b34 error 4 in libc-2.24.so[f7441000+1af000]
|
|
Segmentation fault (core dumped)
|
|
|
|
This is because in source code ./subversion/libsvn_fs_fs/low_level.c,
|
|
function svn_fs_fs__unparse_footer, when:
|
|
|
|
target arch: x86
|
|
apr_off_t: 4 bytes
|
|
|
|
if the "APR_OFF_T_FMT" is "lld", it still use type "apr_off_t" to pass
|
|
data to apr, but in apr source code file apr_snprintf.c the function
|
|
apr_vformatter meet "lld", it would use the:
|
|
|
|
i_quad = va_arg(ap, apr_int64_t);
|
|
|
|
It uses the apr_int64_t to deal data, it read 8 bytes, so the follow-up
|
|
data may be error.
