Big memory leak with ESQL/C library!

My code was not linked with any other library except ESQ/C's. These days I suspected that the program run into a big memory leak. Then I used dmalloc(http://dmalloc.com) to debug it and got the following report: ----------- cut ------------------- ... 1063561110: 149639: not freed: '0x80d6008|s1' (1024 bytes) from 'ra=0x8001a221' 1063561110: 149639: not freed: '0x80d6808|s1' (1024 bytes) from 'ra=0x8001a221' 1063561110: 149639: not freed: '0x80da808|s15' (1248 bytes) from 'ra=0x8006eee7' 1063561110: 149639: not freed: '0x80dc008|s15' (1876 bytes) from 'ra=0x800f437c' 1063561110: 149639: not freed: '0x80df008|s5' (1024 bytes) from 'ra=0x8001a221' 1063561110: 149639: not freed: '0x80df808|s5' (1024 bytes) from 'ra=0x8001a221' 1063561110: 149639: not freed: '0x80e0008|s5' (1920 bytes) from 'ra=0x800f4067' 1063561110: 149639: not freed: '0x80e1808|s5' (1044 bytes) from 'ra=0x800f2723' 1063561110: 149639: not freed: '0x80e4008|s1' (512 bytes) from 'ra=0x800c751a' 1063561110: 149639: not freed: '0x80e4408|s3' (616 bytes) from 'ra=0x800c632c' 1063561110: 149639: not freed: '0x80e4808|s1' (512 bytes) from 'ra=0x800c751a' ... 1063561110: 149639: not freed: '0x8100fe8|s5' (16 bytes) from 'ra=0x800cb1a9' 1063561110: 149639: not freed: '0x8107c08|s1' (468 bytes) from 'ra=0x800f437c' 1063561110: 149639: total-size count source 1063561110: 149639: 11415 344 ra=0x800c751a 1063561110: 149639: 4232 1 ra=0x8007cbca 1063561110: 149639: 4096 4 ra=0x8001a221 1063561110: 149639: 3875 28 ra=0x800f437c 1063561110: 149639: 2618 119 ra=0x8012580a 1063561110: 149639: 1920 1 ra=0x800f4067 1063561110: 149639: 1428 119 ra=0x801257fa 1063561110: 149639: 1248 1 ra=0x8006eee7 1063561110: 149639: 1184 74 ra=0x800cb1a9 1063561110: 149639: 1044 1 ra=0x800f2723 1063561110: 149639: 861 92 ra=0x800f2453 1063561110: 149639: 720 1 ra=0x80065a7c 1063561110: 149639: 616 1 ra=0x800c632c 1063561110: 149639: 352 22 ra=0x800cb1ca 1063561110: 149639: 344 1 ra=0x80069aee 1063561110: 149639: 156 1 ra=0x800477b4 1063561110: 149639: 128 1 ra=0x8002949e ... 1063561110: 149639: 36726 825 Total of 26 ... ------------------- cut ----------------------------------- Since the DMalloc only report 'ra' (return address) instead of source code line numbers, so I think the leaks did not come from my own code. After I bring up a debuger (gdb) to check where those magic 'ra' really locate, I believ I am right: (gdb) x 0x800c751a 0x800c751a <gl_ext_malloc+26> (gdb) x 0x8007cbca 0x8007cbca <_sqrealloc+42> (gdb) x 0x8001a221 0x8001a221 <_findbuf+129> (gdb) x 0x800f437c 0x800f437c <meAlloc+28> (gdb) x 0x8012580a 0x8012580a <gl_cache_registry+266> (gdb) x 0x800f4067 0x800f4067 <ostcb_alloc+39> (gdb) x 0x801257fa 0x801257fa <gl_cache_registry+250> ... I won't list all, but I think these routines above are all ESQ/C build-in, right? My program neet to read a great number of data records and insert/update them into tables, the above is just a sample run processing merely 300 records. In a real run with 100000 data records, will those leaks strave my system? Any comments will be appreciated! -- steven@lczmsoft.com
