This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the address@hidden mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Two memory leaks were found with the help of leaks(1) command in Mac
OS X.
1. `range_table_work.table' in regex_compile (regex.c) is not freed if
the compilation is succeeded. The following patch would fix the
problem.
*** regex.c.~1.187.~ Tue Sep 2 09:10:05 2003
--- regex.c Wed Sep 24 18:28:42 2003
***************
*** 3514,3521 ****
if (syntax & RE_NO_POSIX_BACKTRACKING)
BUF_PUSH (succeed);
- free (compile_stack.stack);
-
/* We have succeeded; set the length of the buffer. */
bufp->used = b - bufp->buffer;
--- 3514,3519 ----
***************
*** 3555,3561 ****
}
#endif /* not MATCH_MAY_ALLOCATE */
! return REG_NOERROR;
} /* regex_compile */
/* Subroutines for `regex_compile'. */
--- 3553,3559 ----
}
#endif /* not MATCH_MAY_ALLOCATE */
! FREE_STACK_RETURN (REG_NOERROR);
} /* regex_compile */
/* Subroutines for `regex_compile'. */
2. `fontp->font_encoder' in fs_load_font (fontset.c) may be overridden
by
if (find_ccl_program_func)
(*find_ccl_program_func) (fontp);
without being freed when `fontp' is already an element of
`dpyinfo->font_table' in x_load_font (xterm.c) and has non-NULL
font_encoder.
