Subject: [nasm-devel] tool to help find memory leaks Date: Fri, 02 Nov 2001 22:08:01 -0500 From: Ed Beroset <[email protected]> Reply-To: [email protected] To: [email protected] Here's a little Perl script I wrote a while ago to help track down memory leaks in nasm. First, compile nasm with LOGALLOC defined (see nasmlib.c). That creates a log file of all allocs and frees. This Perl script reads that file and tells you which source code lines caused a leak (or a free of unallocated memory). There are many leaks, almost all of them in the preprocessor. -+--- findleak.pl begins #!/usr/bin/perl my %mem = {}; my %alloc = {}; while(<>) { if (/realloc\((0x[0-9a-f]+).*\).*returns \((0x[0-9a-f]+)/) { $mem{$1}--; if ($mem{$1} != 0) { print "free before alloc! $_"; } if ($mem{$2} != 0) { print "memory leak! $_"; } $mem{$2}++; $alloc{$2} = $_; } elsif (/free\((0x[0-9a-f]+)/) { $mem{$1}--; if ($mem{$1} != 0) { print "free before alloc! $_"; } } elsif (m/returns (0x[0-9a-f]+)/) { if ($mem{$1} != 0) { print "memory leak! $_"; } $mem{$1}++; $alloc{$1} = $_; } } foreach $goo (sort keys %mem) { if ($mem{$goo}) { print "$mem{$goo} $alloc{$goo}"; } } -+--- findleak.pl ends Your use of Yahoo!
