gcov crashes

[Jindrich Kubec]

Problem: gcov crashes on one of the files

Compiler: gcc version 2.95.3-5 (cygwin special), gcov 1.5

Platform: Windows 2000, cygwin, out of the box (binaries, no patches/custom 
build)

Description:
I'm compiling all sources with these options:
-c -fno-exceptions -fno-rtti -fvtable-thunks -fverbose-asm -Wall 
-Wno-format --save-temps -finline -finline-functions 
-fno-keep-inline-functions -Winline -fbuiltin -mcpu=i386 
-mpreferred-stack-boundary=2 -g -pg -ax -fprofile-arcs -ftest-coverage

I'm getting *.bb, *.bbg and after I run the executable, also *.da files.

I'm running gcov filename (no suffix). It works on all files, except for 
one where it immediately crashes: STATUS_ACCESS_VIOLATION.

Source file need not be present for this bug to happen. I could send you 
*.bb, *.bbg, *.da files for you to check, but not the *.cpp, sorry. (Also 
*.da file is not needed for bug to appear).

Any hints?

I tried to isolate the problem by commenting out portions of the code, but 
it gave me rather unpredictable results - sometimes it crashed, sometimes 
not, sometimes it reported unexpected EOF.
